Polt

Polt is a female Kobold, the leader of Kobold Industries and coordinator of the extra-species health spa, Sports Club Kobold and the Kobold Stadium. She is also known to work with Smith by watching Liminals that break the law and are on probation. She debuts in Chapter 17 where she help Cerea, Miia and Mero lose weight.

Appearance
As with all female Kobolds, she appears as an almost human woman with a wolfish nose, tail, ears, and covered in fur. Her body, in accordance with her occupation, is very athletic; having muscular arms and legs and a trim abdomen. Her breasts, while still quite large and well-endowed, are more "normal" size, in comparison to other characters' more prodigious breast sizes. In her debut, she wears a midriff revealing black shirt with the sports' club's name on it and an unzipped track coat on top; denim hot pants; thigh straps and wristbands; a dog collar and athletic sneakers.

Personality
Like most stereotypical workout coaches, she has a very hyper and chipper personality that is willing to help anyone succeed in their exercise routine. She is always cheery and optimistic, and is always glad to help people work out.

Polt seems to have a general need to help others, which can clearly see from the fact that she is always keen to adapt her gym to the special needs of the various Liminals. In this respect, Polt can be seen as a very open-hearted and tolerant person. In addition to sporting activities, Polt also seems to be very concerned about the general welfare of others, as can be seen from her efforts to clean Kii's Forest of the trash after learning that Kii was not doing well. However, Polt can also be a little naive at times, as can be seen in Chapter 43 and Chapter 48, when she did not see what was really drawing the eyes of the onlookers.

While Polt is generally not easy to be disconcerted and is always optimistic, Chapter 41 seems to indicate that this is partly a facade to hide her own vulnerability and sensitivity. When Polt was under the influence of Tio's motherly aura, she said sadly that the reason why no one came to help her clean up Kii's forest was maybe because no one liked her. She was also moved to tears when Tio assured her how much she had already done for the Exchange Between Species Bill, which shows that Polt is sometimes unsure about whether she has done enough to help others, even if this is the case.

Polt strives to enforce her principles for a health experience to support humans and Liminals, but this also means that there are certain business sectors where she finds her limitations. When Kobold Industries got the order to build a casino, Polt was not satisfied with this new business move and later tried to come up with ideas that would make the casino more in line with the concept of Kobold Industries. While the idea ultimately fell through and meant a financial loss, Polt also saw the positives as their company was able to maintain their ideals.

While Polt is willing to show her body off to a certain extent, she will only go so far before acting up in embarrassment; she was fine with wearing a form-fitting playboy bunny costume and a one-piece swimsuit, but was far from pleased at wearing a bikini.

Personal Skills

 * Athletic Training: As a health spa coordinator, Polt is very fit and athletic. Her daily exercises include running the length of a marathon (42km). Polt also knows enough about swimming to teach classes to those who frequent her gym. Her own swimming skill might be more questionable as her default swimming style is the doggy paddle. She is knowledgeable about other people's bodies and how they perform athletically. She lacks other knowledge, such as that a heated pool can still cause the body temperature of cold-blooded species to fall, and that chlorinated water is toxic to merpeople. However, she is willing to learn about such things in order for her health spa to treat all Liminal species.
 * Mind Training: As Polt explains to Kimihito in Chapter 41, she not only trains her body, but also her mind, whereby she represented the motto that a sound mind in a sound body is important. Polt also assured Kimihito that no kind of temptation could defeat her, but in practice this turned out to be untrue, at least when it came to Tio's maternal aura, as Polt almost immediately fell into her calming presence and became tired and lethargic, unlike her always such hardworking nature.
 * Economics: Because of her species' numerous financial endeavours, Polt knows how to run multiple profitable businesses simultaneously.
 * Wilderness Survival: As Polt spends a great amount of time taking part in outdoor activities she knows a number of wilderness survival skills. This includes gathering food by fishing and how to extract water and nutrients from plants and plant-like beings like Kii.
 * Digging: As seen in Chapter 25, Polt can use her paws to dig a hole in a matter of moments, reaching from the depth to her hips, in which she planned to bury the catfish, before Kimihito asked her if he could take the fish with him.

Physical Traits

 * Kobold Physiology:
 * Heightened Senses: Her physiology makes Polt's senses of smell and hearing far above those of a human. Her nose can determine whether a person has exercised to their full potential, based on the changes in the smell of their sweat. Her hearing is able to pick up very faint sounds and is 4 times as good as a human's.
 * Paws: As a Kobold, Polt has paws with soft padding twice the size of human hands. Her nails are naturally razor sharp, but like most Kobolds, Polt smooths them down with a nail file since she has no use for them.
 * Tail: The tail of a Kobold portrays their emotions, they wag it when they are happy. However, this happens reflexively and it is impossible for a Kobold to actively suppress.

Plot
After a medical examination reveals that a lack of outside activities and an abundance of Kurusu's food has set Miia, Centorea and Meroune's bodies out of balance. On arrangement with Ms. Smith, they head to the only known extra-species health club that was newly built, Sports Club Kobold, owned by Polt.

Here, Polt excitedly gives the girls a free preview so they can exercise and test out the facilities for her. Despite being relatively well furnished, once again it's revealed that demihuman extra-species are at times involuntarily discriminated against, as most exercise machines are designed for human-sized bipeds. As they are unable to use most of the exercise room (other than the free weights), they go swimming in the pool instead. Once there, she has the girls put on provided swimsuits suited to their body types and has them stretch out before entering the pool.

When Miia and Mero have a discussion about their swimming styles and make a bet with the winner having a technical carte blanche with Kurusu, Polt acts as the announcer. She soon finds out that despite being a heated pool for poikilothermic species, swimming still cools the body down gradually thus draining Miia of her energy and chlorine is toxic to merpeople which almost poisons Meroune. As such, she tells the group that she plans to add a sauna, make the pool warmer and treat it with ozone instead of chlorine for purification, and just keep the exercise machine room for bipeds.

Some time later Kurusu and Suu come across Polt with Draco doing community service by fishing for American catfish in the river, which is an invasive species in Japan. When they ran out of bait she wanted to bury the ones they already caught until Kurusu asked if he could have them. She agrees and helps prepare the fish for transport.

When Centorea challenged her mother to a jousting duel, Ms. Smith called Polt to borrow the use of Kobold Stadium, which is owned by Sports Club Kobold. Polt and Smith acted as announcers and commentators for the duel, which was televised by the stadium to the "thirty million centaurs around the country."

Later on, while on a 'date' with Tio in the forest, Kurusu runs into Polt again, as she is overseeing the cleanup in Kii's forest as part of the community service for interspecies program. Unfortunately, due in large part to Doppel's antics the day before, her two probationary helpers Lilith and Draco are no shows. Instead, Kurusu ends up helping Polt clean while Kii relaxes with Tio.

Afterwards, the two break for lunch, Kurusu taking the liberty of informing Polt that Tio's 'Warm Aura' is dangerous. In spite of Polt's claims of mental fortitude, she is quickly defeated by Tio's scratching her ears and caught in her embrace as well while Kurusu continues to clean. After Tio tears out an old augur that someone dug into the forest and never removed, the entire area spontaneously turns into a hot spring thanks to a underground spring of water and the group decides to bathe in it.

Although it took some convincing, Polt was able to get Kii to let her build a health spa in the area so long as it does not have a serious impact on the environment. Kurusu and Centorea subsequently use the sauna she built to trap Killa who had been chasing after them.

Polt, alongside several other Kobolds, is seen in the Inter-Species Cultural Exchange Exposition hosting an event representing Sports Club Kobold. When Kimihito approaches her, Polt proceeds to demonstrate their latest product, a "Centaur Riding Machine". As Polt starts getting sweaty and worked up, she starts attracting the attention of numerous male attendees, unaware of what really draws them towards her. In Chapter 64 it is revealed that Polt and Poltfan had married and were supposed to be helping out at the Sno Ball Hot Spring Resort but were on a business trip to the states to open up gyms and do sports related business (with Poltfan acting as her official interpreter), leading to Kimihito and his homestayers to cover until they got back.

Zoological Classification
Kobolds are pseudohuman beings that possess canine physical characteristics and traits.

Abundant in German folklore, Kobolds are known for mining rich veins of Cobalt; a mineral used in certain alloys and small electronics. As such, many kobolds have earned themselves a small fortune in processing and selling cobalt on the market.

Possessing coarse fur covering their bodies, a kobold's ears are around 4x more sensitive than a human's while their sense of smell is easily 1000x times more sensitive. Female kobolds are more humanoid than males of the species, the latter which appear more bestial and less anthropomorphic.

Trivia

 * Financially well-off, due to her species' association with mining the mineral cobalt, Polt owns and manages more than just the Sports Club Kobold and Kobold Stadium. She manages a variety of businesses, such as spas, massage parlors, relaxation centers, and more.
 * In the official Seven Seas translation, her name was initially translated as Port. This may be due to R and L sounding very similar in Japanese accented English. It has, however, since been retranslated as Polt, most likely to better fit with her races' name.
 * Polt actually has extra nipples hidden within her body fur, as revealed in her secrets.
 * In many chapters it's revealed that she is in charge of disciplining wayward exchange monsters without any supervision from the Cultural Exchange Security Squad or Ms.Smith,
 * Due to her popularity and specific wishes that she be included from her fans, Okayado insisted with producers that Polt make an appearance in the anime series, even if her introduction chapter was not included. As a result, Polt makes three cameo appearances in Episode 10 of the anime show. She also makes a blink and you miss it cameo in ep 11 during Manako's date.
 * MonMusu Anime Twitter account revealed that her Birthday is February 7th.
 * Kobolds are depicted as canines in Eastern culture due to the original 1st edition book depicting them as such. While the image of the race later evolved to be more reptilian in western culture, in eastern culture they remained as they were originally depicted in Dungeons and Dragons.
