Centorea Shianus

Centorea Shianus (セントレア・シアヌス, Sentorea Shianusu), also known as "Cerea" (セレア, Serea), is the third resident of Kimihito Kurusu's home. She is very prim and proper, referring to herself as a self-proclaimed knight.

Appearance
Cerea is a fair-skinned centauride with sky blue eyes and very long blonde hair, which is always in a high-ponytail. As is typical for a female Centaur, she has rather large breasts.

The most noticeable trait in her appearance is her headless horse of a lower body, and her long and pointed horse ears. As she's very modest, she usually wears unrevealing clothes that covers her torso which only leaves her shoulders exposed and puts on a full set of medieval armor for special occasions. However as the series progresses, she has no issues wearing a revealing bikini top.

Personality
As one of the noble creatures, Cerea is incredibly honorable and chivalrous, while being unerringly loyal to Kimihito. Also, she is somewhat archaic in speech and behavior. Centaurs have strict rules about only letting one's master ride on their backs. Naturally, Kimihito finds this out right after he spends most of his time riding on her back, as if she is a war horse. Before Kimihito became her master, she threatened him with throwing him off her back when he accidentally grabbed her breasts.

As a foreign creature outside Japan, Cerea seemly has troubles of grasping Japanese culture, as she mistakes certain scenes from anime/manga as Japanese tradition, including the "fated" meeting when someone runs into another with toast in their mouth.

While she usually does not show much affection, she is in love with Kimihito just like the rest of the girls. Although she isn't as sexually intimate with him as Miia and Rachnera Arachnera‎‎, it is hinted that she wants to further her relationship with him, as when Kimihito told her and Miia to think of Suu as a child, she briefly fantasized of having had a child with him. Despite this, she reprimanded herself for the thought of having a child with her "master", meaning she puts her duty as Kimihito's "knight" above everything else.

Alongside Meroune Lorelei, Cerea is the most level-headed of the harem, often trying to remain calm and composed no matter the circumstances and keeping the others in line if they go too far, especially Miia or Rachnera. Despite this, she is also the most easily flustered when in an intimate moment with Kimihito, sometimes even losing complete track of her surroundings. Also, she has been shown to be just as possessive of Kimihito as Miia, the difference is that Cerea hides it much better and can seemingly be ashamed of it.

She seems to have strong willpower, as seen when the full moon appears. As opposed to Miia or Papi, Centorea seemed to be able to resist its effects, but only for a brief moment; after she succumbs to the moon's effects, she started behaving in a more seductive way towards Kimihito, also injuring Kimihito after losing her conscious control over her immense strength.

She is also very defensive of her self-proclaimed "master", trying to defend Kimihito from Suu when she first appears attacking people. She also has a small fondness for RPGs.

Cerea also seems to be rather shy when naked around Kimihito, as she accidentally kicked him when he walked in on her when she was showering but regretted her action immediately, or when she was embarrassed to ask him to help her wash off after Suu covered her in slime. Also, despite her large breast size, she feels inadequate when faced with someone even more developed than her.

While Centorea's self-serious personality is usually charming, her inflexibility can also prove problematic. This was particularly evident early on during Centorea's work at Cafe Marsha during the Pilot Program, as she found it difficult to perform even a simple gesture like "Moe-moe-kyun", not considering herself such a "weak, childish moment" wanted to allow. Generally, Centorea tends to want to perform perfectly over and over again, but this can often cause problems, especially in regards to Centorea's impatience when things get difficult for her.

Due to her horse physiology and nature, Cerea's favorite food are carrots. She tries to hide her big appetite for the vegetable because people make fun of her for it.

Personal Skills

 * Archery: She is also skilled with a bow and arrow; able to pin Papi to the wall with precise aim.
 * Cooking: Centorea is a better cook than Miia, however her specialty is fruit and vegetable salad.
 * Indomitable Will: Centorea seems to have a rather strong amount of willpower, as she is able to resist the effects of the full moon, if only for a brief moment. However, after holding out long enough to save and warn Kimihito, she then immediately falls under its effects and behaves in a more seductive way towards him just like Miia and Papi.
 * Master Jouster: Centorea is very skilled at jousting, though she is still not quite able to hit the center of her opponent's shield during duels without assistance, as her large breasts get in her way. She duelled her mother to a draw. This is quite the accomplishment as her mother was undefeated in the sport, is considered the best in the world and holds the title of "the Goddess of Jousting". Centorea often practices jousting by the river near the Kurusu house.
 * Perception: Centorea is a very good judge of character, as she was able to deduce from Ms. Smith's and Meroune's mannerisms that the latter might be of noble or even royal lineage. This was later proven to be correct, as Mero is a princess.
 * Martial Arts Training: As Centorea reveals in Chapter 45, she was knighted by her mother from an early age and taught martial arts by her.

Her skills extend to other bladed tools as well, as she was able to use two sickles to fully shear a Pan Faun in just a few fast slashes.
 * Swordswomanship: Centorea is very adept at swordplay, and is capable of making multiple rapid and precise slashes. This, combined with her strength, makes her capable of easily slashing through several plastic water gallons with a dulled sword, and cutting doors to pieces. She is skilled and strong enough to easily wield a two-handed Claymore with only one hand, and is precise enough to cut a falling leaf in half with her eyes closed. Her skills with a sword are so great, that she can effortlessly defend both herself and Kimihito from a swarm of angry Giant Hornets by rapidly cutting each insect in half with a large claymore..

Phyical Traits

 * Centaur Physiology:
 * Centaurs Ears: A Centaur's ears are capable of reflecting the centaur's mood as they are able to move much in the same way as a horse's ears.
 * Agility: She also has great speed and agility. She is able to keep up with a speeding scooter, while carry a full grown human on her back. Her top speed is said to be 60 km/h (37.2823 mph).
 * Durability: Centorea is shown to be durable enough to jump through a second-story window at high speed and land on the ground without any noticeable effect on her.
 * Herbivorous: Centaurs are herbivores, as Centorea has said she can only eat fruits and vegetables, and not things like eggs or fish. She has twice the amount of taste buds a human does so the taste of food is much stronger for her.
 * Large Breasts: She claims her large breasts are a common norm in female centaurs since centaur babies require a lot of nourishment. Because their babies are born larger than human babies at birth, female centaurs have evolved to grow enormous breasts to increase their milk content. When her mother visits her, she is also shown with a really large bust.
 * Breast Milk: As revealed in Chapter 71, Centorea was able to produce breast milk for a brief moment in extremely stressful situations even without being pregnant. However, this appears to be a very rare occurrence as Centorea was unaware of it since it has never happened before.
 * Normothermia: Like horses, she has higher body temperature than Humans. Hers is 38°C (100.4°F) to be precise. This is the same as the average horse.
 * Strength: Centorea possesses inhuman strength, both in her horse half and her human half. She has been seen effortlessly lifting both Miia and Mero with one hand each, at the same time. She is also strong enough to use a log as a weapon to knock a wild boar unconscious. She also displayed her strength during the full moon, when she broke the table and the floor by just stomping on it with a single hoof. It has been stated that her family contains some of the strongest centaurs in the world.
 * Sense of Smell: As Centorea reveals in Chapter 71, because of their equine biology, Centaurs have a sense of smell that is 1000 times greater than that of a human.

Possessions
See Also: Centorea's Weapons
 * Armor: Centorea possesses a full suit of traditional, medieval Centaur armor, designed for women.


 * Shield: To finish the set, Cerea also owns a large shield with a horseshoe emblem on it, encircling a fleur-de-lis and underlined with scripted banner.


 * Saddle: Centorea recently acquired a saddle so that Kimihito can ride her more comfortably. Given Centaur traditions and restrictions on letting humans ride them in such a manner, it's kind of a big deal for her when she wears it. It came loose almost as soon as she used it. She stores it on a short, wooden-framed saddle rack in her room.


 * Weapons:
 * Replica Swords: Centorea is known to possess at least four fake, two-handed Claymores, which she can easily wield with just one hand. One of them is a replica of Andúril, from The Lord of the Rings.
 * Bow and Arrows: She also owns at least one bow, alongside a quiver full of arrows.
 * Lance: She is shown to be in possession of a medieval lance for Centaur jousting. She also owns a training lance and a training dummy for practice.

Plot
She was given special permission to go out without a host escort to search for a "master" and accidentally runs into Kimihito in the streets while searching for her "master" (with a sword), and immediately picks him. During their conversation, a biker steals a lady's purse, to which Centorea gives chase with Kimihito on her back to assist her. After a long chase and several hijinks, they cause him to crash into some paint cans, but they crash as well. The thief tries to strike Centorea down with her own sword, but Kimihito jumps in front of her and takes the blow. He survives (due to the sword being fake) and later on at his house, Centorea gains new respect for Kimihito as he is the first person to lay their life on the line for her and offers to become his servant, becoming the third resident at his house.

Later Centorea and Miia got into a fight when Miia tried to assert her dominance over the group by claiming that Kimihito belonged to her since she was the first resident of the house. The fight got even worse when it continued in the park and when Papi joined the fight. As the fight was about to break out between the three in the park; Sumisu quickly got involved and tried to shoot them with her tranquilizer gun in order for them to not accidentally injure anyone, only for Kimihito to take all three shots unknowingly. Cerea and the others later apologized for their behavior.

When Kimihito had been made into the guinea pig of a new amendment to the exchange program, allowing inter-species marriages, which presumably rendered the rule of "no inter-species sex" invalid, Ms. Smith introduced the inter-species marriage addendum. Unfortunately, this happened on the night of a Full Moon which awakened Cerea and the other monster girl's more primal instincts, resulting in Kimihito spending the whole night trying to avoid them all.

When Miia first attempted to cook, she accidentally poisoned Cerea and Papi with her horrible food. This incapacitated them and left them unable to warn Kimihito about eating the food.

Later, when Miia was trying to improve her cooking skills, a Slime Girl snuck into the house, knocking Miia out. Cerea immediately attempted to protect Kimihito by slashing the slime with her sword. When this had absolutely no effect, Cerea was surprised, as Slimes tend to be the weakest enemies in RPGs. The slime quickly disappeared. Later Cerea, after asking permission from and being granted by Kimihito, joined him in a bath which he was taking. Embarrassed, she explained she is trying to protect him in case the Slime attacked again. Though this point proved moot, as she was quickly knocked unconscious when the slime reappeared.

Later, the Slime, now named Suu by Papi, continued to cause trouble around the house, accidentally absorbing many objects around the house and getting slime everywhere. While Cerea and Miia were angry at her and suggested bringing her to Ms. Smith; however, Papi quickly fled away with her. Miia and Cerea attempted to give chase, only for Ms. Smith to arrive.

Later on Kimihito had decided to let Suu stay with them. At first Cerea and Miia were hesitant about it, but quickly changed their minds when Kimihito told them to think of her as a child which caused Cerea even to think of a having a baby with Kimihito someday (much to her own embarrassment); however, when Kimihito arrived home, Miia told him a little too late that Ms. Smith had arrived, culminating in the encounter with Ms. Smith which they had wanted to avoid.

Almost immediately Miia, Cerea, and Papi started panicking over what Ms. Smith would do to Suu, but Kimihito was too busy with the remodeling of his home to pay too much attention. Despite him thinking the remodeling was for Suu, the three of them took her and hid in the park, all the while hiding from what they thought were Smith's "minions" (in reality they were Meroune's escorts). She along with Papi and Miia got themselves wet causing Suu to knock them unconscious one-by-one by assaulting them for moisture. In the evening, a room with a pool had finished being built. Centorea, Kimihito, and her fellow houseguests were surprised that a wheelchair girl whom he rescued earlier was moving in to the Kurusu house by Smith's arrangements. The wheelchair girl revealed herself to be a mermaid formally introducing herself as Meroune Lorelei.

The next day, Centorea saw Miia breaking the wheelchair as the lamia was fighting for Kimihito's attention. After the centaur made a phone call to Smith and telling him that the coordinator would bring a replacement wheelchair as soon as possible, she became aware of how agitated Miia was when Kimihito had to carry Meroune bridal style. Miia brought up the flaws of her fellow houseguests including Centorea never trying to seduce him. This caused the centaur to say, "Why don't you tell us how you really feel, Miia? Besides, you don't even know if she's interested in him." To the surprise of Centorea and Miia, Meroune flirtingly asked Kimihito if he had a wife or lover. Despite a mishap occurring, the centaur discovered the reason why Suu attempted to assault the mermaid earlier. Later in the living room, Centorea saw Miia scheme to freeze the mermaid by setting the AC's temperature to the lowest and seeing that it backfires with the lamia freezing to the extent of her coming close to entering hibernation. Furthermore, the centaur heard that Meroune was unaffected by cold temperatures when Kimihito brought the mermaid into the living room. Before he left Meroune with her fellow houseguests, he set the AC's temperature to the highest and could not adjust the temperature as the remote was out of batteries. Centorea questioned Meroune's curiosity on his relationship status, but the mermaid brought out the story of "The Little Mermaid". The centaur guessed that the mermaid came from a royal family as she imagined herself as a knight standing before a queen due to an aura in which the mermaid unwittingly projected. After Kimihito returned with the batteries, he had Miia change the remote's batteries while he took Meroune back to her room. Centorea then made it to clear to Miia, "That's quite enough, Miia, let it go. If you don't like what Master is doing, then you shouldn't have broken her wheelchair." After Centorea heard how Miia enjoyed fairy tales and the lamia's desire to be carried bridal style, the centaur was doubtful on whether it would work or not. Eventually when Centorea and Papi overheard a conversation between Miia and Meroune from outside the bathroom, the centaur said, "We'd better not underestimate her."

One day, Kimihito returned home from grocery shopping and Suu displayed affections towards him causing Centorea to say, "Stop that, Suu! Give Master some space, he's exhausted!" Papi announced that she was going to lay an egg and startled her fellow houseguests who beat him up until they realize that the egg was unfertilized. A man who claimed to be a Kasegi barges into the Kurusu house without Kimihito's permission to do a documentary on interspecies exchange. Kasegi notes how classy the centaur's Japanese style room was and asked her an uncomfortable question causing her to draw her sword if he was going too far. When Kimihito prepares to help Papi with the egg laying; Suu uses mind-reading to blow Kasegi's cover broadcasting his true sinister intention, angering Miia, Centorea, and Meroune. Before the centaur and her two fellow houseguests attacked, their beloved host used a normal chicken egg he purchased from the supermarket to trick the conman whom he punched in the face. Kimihito also destroyed Kasegi's camera and the footage during the process. Centorea notes her impression on Suu's mind-reading ability before Miia blindfolded Kimihito so that Papi could complete the egg laying. Smith later informed Kimihito that the self-proclaimed director's name and card were fake. Miia boiled the harpy egg for dinner to everybody else's horror.

One day, Centorea along with her fellow houseguests and their beloved host watched the news about the Orc threat in the Doujin shop. After seeing how Smith and her Interspecies Exchange security squad handled the threat, the centaur commented, "Those wretched lowlives, they're supposed to be acting as ambassadors of their kind."

The next evening and after Smith informed the Kurusu houseguests about a non-human living with the conman director, she then asked about Kimihito and Centorea replied, "He should be home anytime, they're having a big sale in the supermarket." Smith and the Kurusu houseguests were shocked to find that Kimihito had not returned, but there were food materials on the entrance.

Later, on, Centorea would butt heads with Rachnera, seeing the arachne as a threat to Kimihito's safety, however afraid to voice her opinion on this. Throughout the day, Centorea would keep extremely close to Kimihito, using his status as her 'lord' as an excuse.

Eventually, Rachnera wears Centorea's patience thin, attempting a 'romantic rendezvous' in the middle of the night. This causes the centaur, who was listening in, to immediately break down the door and grab her host, breaking down the wall and galloping away as far as she could. However, various stares cause her to remember her own discrimination (albeit, most of these stares were actually at her breasts), she then stops galloping, only for the male of the racist couple, among with what appears to be various gang members, restrain and attempt to molest her. This prompts Rachnera to reveal she had followed, using sheer intimidation tactics to knock the attackers unconscious, Centorea is grateful until the arachne continues her attempts to have her way with Kimihito, causing Centorea to kick Rachnera and reveal her own hatred. Rachnera merely laughs, revealing she knew the whole time, stating she would prefer that the centaur just be honest, as she knew her own intimidating demeanor. The two end up forming a kind of friendship, although Centorea still gets annoyed with Rachnera at times.

One day, Centorea and her fellow houseguests were shocked to find their beloved host bedridden with a cold. After Smith had the house quarantined due to her claims about the virus transmitting to non-humans, she slacked off causing the Kurusu household to take things into their own hands. At Meroune's suggestion, Suu shapeshifted into Kimihito so that the girls could teach the slime how to be a good caretaker. Centorea taught Suu how to take his temperature, however the centaur was flustered towards the shape-shifted slime that resembled Kimihito. Subsequently, Suu nearly drowned him when she attempted to take his temperature then claimed that his fever was over one hundred. Later, Centorea along with Papi and Rachnera were horrified by Miia's bad cooking in which Meroune got food poisoning from. The centaur along with Miia, Papi, and Meroune lost self-control due to their growing intimacy towards the shape-shifted Suu causing Rachnera to tie the four of them up. As a result, Suu nearly freaked their host out. Eventually, Centorea and four of her fellow houseguests found that Suu managed to cure their host. However, Smith caught a cold afterwards.

One day, Centorea and four of her fellow house guests had a tail on their beloved host to a maid cafe where he was on a date with Smith. After the girls' attempts on spying, the coordinator informed all the Kurusu house guests that he received a murder threat letter and called in favors to have the girls to go out on a date with him in order to lure the culprit.

When it was Centorea's turn to go on a date with Kimihito, she was overprotective of him to the extent of wearing her armor and yelled at Manako (who was the surveillance agent) over the phone. He noted on how scary the armored centaur was in public, so she obliged by taking it off. While visiting a video game store, Centorea had difficulty entering through the doorway and accidentally knocked over a box of balls. After Kimihito suggested outdoor activities, the centaur accidentally sent him flying, knocking over another box of balls. Later in a park, Centorea brought out sandwiches she had prepared earlier for a picnic. Rachnera (who had been watching out for them) exposed Kimihito's compliment on one of the sandwiches as a lie because he did not want to hurt the centaur's feelings. After Centorea noted that centaurs could only eat vegetables, she felt bad for being a failure. When Centorea went off to clear her head, someone hypnotized her into behaving in a lewd manner to Kimihito who nearly freaked out and lost consciousness. At the time that someone was attacked by a large wild boar, it snapped Centorea out of the hypnotism, enabling Kimihito to throw his sweater at the boar's eyes so that it would crash into a tree. When the boar targeted him, the centaur defeated it by using a log like a lance to knock it out. However, Centorea felt bad for causing him more trouble and was only useful when cleaning up her messes. Kimihito mounted the centaur due to his ankle being twisted when fleeing the boar and mollified her that he counted on her all the time. After Centorea gave him a ride home, she made dinner consisting of salad to the dismay of Miia and Papi whereas Meroune did not mind. The centaur was pissed off when the lamia and harpy fed their portions to Suu.

Zoological Classification
The Centaurs (ケンタウロス族, Kentarosu-zoku) are a demi-human liminal race with the upper body of a human and the lower body of a horse. Herbivores, centaurs are normally found in grasslands and savannas, and are a race of nomads who become brave warriors in times of conflict.

Their civilization is ancient, by far the oldest of all the humanoid races known to mankind. Extremely proud and strong-willed, they differ from the other races in that they consciously suppress their urges during mating season.

Trivia

 * Centorea goes on "morning gallops" and has a bath shortly afterwards every morning before Kimihito wakes up at around 6:30 am.
 * Centorea, Meroune Lorelei and Rachnera Arachnera are the only Monster Girls currently known to have a last name; the first two also belong to noble houses.
 * Her name is derived from her species name: "Centorea" from Centaur. In chapter 10, her romanized name is shown to be "Centaurea", closest to her race, but that didn't catch on even in the official translation, so it was changed. Also, her name may be derived from the scientific name of cornflower; Centaurea Cyanus.
 * As a consequence to her horse physiology, Centorea is the heaviest of the homestays in the Kurusu household, much to her dismay and embarassment.
 * Centorea loves carrots but she doesn't want to reveal it due to believing that she would be made fun of if everyone knew. Lately she's been into Kintoki carrots.
 * According to Miia, Centorea's breasts are her most attractive physical trait.
 * In the same omake, it is explained that her very large breasts are due to baby centaurs being much larger than normal offspring, with mother centaurs needing bigger and larger breasts to satisfy their needs. However, this explanation seems to be flawed. Breast size is usually determined by how much fat cells are in the breasts. The only way her reasoning could be true is if her mammary glands were bigger and more productive and even then, as a virgin, her milk-ducts are not fully developed and would not be until late into her first pregnancy. Of course, since Centaurs are different from humans and since Centorea is not entirely human, her reasoning can also be supported by the fact that their growth and anatomy are different from humans, and likely also their biology.
 * Her breast size is larger than 103 (an I-cup bra in Japan), which is the cup size of the bra that Miia bought for her (in the special from chapter 17) and the bra she ordered herself (in chapter 29), which were still too tight for Centorea.
 * Cerea does not wear bras or any form of underwear. It's not customary for Centaurs to do so. She did however wear a bra purely for support when she jousted with her mother.
 * In the case of bras, the main reasons why she doesn't wear them is because: 1) her incredibly large breast size; and 2) she claims they have smaller measurements than they actually have. So any bra she wears is always too small.
 * As opposed to Miia and Mero, Cerea's genitals are on her animal half, as opposed to her Human half.
 * Strangely, despite this revelation, when Cerea imagined herself pregnant, it's clear the fetus is developing inside her Human half, which would be very inefficient, impractical and even very dangerous for both the mother and the child. It's also strange that earlier, Cerea mentioned Centaur babies are quite large, so it makes even less sense. Okayado most likely "translated" her thoughts so the audience would understand, as we would not recognize a pregnant "horse".
 * Centorea resembles Arturia Pendragon from Type-moon's Fate franchise in terms of facial appearance and a bit in personality (Noted: while Saber is more cold and merciless, both Saber and Centorea are very prim and proper women, uphold knightly-cavalry codes of honor and are easily flustered by even the lightest teasing), and Winry Rockbell from Fullmetal Alchemist in terms of hair styles.
 * She also refers to Kimihito Kurusu as her "Master" just like how Saber refers to Shirou Emiya as her Master.
 * She is the first monster girl to possess and use weaponry.
 * Centorea was unaware until recently that she is actually born of mixed blood, as her father was human. It remains a mystery if that means her offspring, as she's not from a female-only race, can be more humanlike or be more centaurlike.
 * Centorea's room is decorated and furnished in traditional Japanese-style, known as washitsu or nihonma. She doesn't need a bed so she chose tatami mat flooring to sleep on. She also likes the grass-like smell of bamboo. Her armor and weapons are kept on stands.
 * On Twitter the author drew her cosplaying as Ms. Baker from Gundam Build Fighter and Petra Ral from Attack on Titan, previous roles of Natsuki Aikawa.
 * Profile Stickers and MonMusu Anime Twitter account revealed that her Birthday is November 28th.
 * She has a devotion complex, always imagining that she will stall enemies for her master to escape, just like Mero's tragic complex.
 * Her birthday places her under the Sagittarius Zodiac, a further reference to her Species as Sagittarius is depected as a Centaur Archer.
 * As officially confirmed in Chapter 71, Centorea is a virgin.
 * Although Centorea accepted Kimihito as her master, he strictly speaking never agreed to her oath of loyality, as Miia and Papi interrupted the conversation between the two before Kimihito could agree or decline.
 * Even though Centorea is classed as a centaur, she is actually a hybrid as her father is a human.
 * Kimihito admits to himself that, due to their size, he sometimes mistakes Centorea's skirts for blackout curtains when he does the laundry.
