Suu/Relationship

These are the various relationships Suu has or had over the series. Suu has an odd relationship with most characters, due to the nature of her species. A running gag is that she will inappropriately (in the most comical and most erotic manner) molest any female character covered in liquid in order to absorb their moisture. This also includes violating her own friends as well.

Kimihito Kurusu
"Well, it was Suu's fault that you caught a cold... I should apologize as well. But Suu doesn't mind! Because she loves her Master!" - Suu talking by herself for the first time.

Like most of the other homestays, Suu is in love with Kimihito. Suu values Kimihito's safety and health above all else, even willing to go as far as to use her own water-absorbent body to heal his sore throat, as well as ingest a variety of poisonous plants to keep him, and by association the other house guests, from getting sick off them. When Kimihito was suffering a dilemma on who to marry, Suu naively suggested that he should practice polygamy.

Suu fell in love with Kimihito after he showed kindness to her by giving her his umbrella when she was outside during a rainy day. This resulted in him catching a heavy fever and being bedridden. Suu knew that she can cure his ailment by feeding him purified water from her body. After he was healed, she finally spoke in her own words and voice by announcing her being the one to blame for his illness, but does not mind apologizing because she loves her "Master."

Like Papi, Kimihito tends to view Suu as a child or "little sister" as opposed to a potential marriage candidate. He sometimes gets a bit irritated when Suu unintentionally suffocates/drowns him through her embrace.

Kuroko Smith
While the other house guests were scared of Smith discovering Suu and deporting her, the agent's decision to turn a blind eye due to sheer laziness has left Suu with a positive attitude towards Smith, though after absorbing poisonous plants, she venomously and bluntly refers to her and her teammates as a bunch of "freeloaders."

Neighborhood Kids
After escaping with Papi, Suu was introduced to the Neighborhood Kids. Her first instinct was to copy Papi embracing the boys of the group, after expanding her body with water, to imitate her. When one of them was about to be run over by the Racist Couple driving, without any mimicry involved, Suu jumped into the path of the car, and saving the young girl.

The Racist Couple
While Suu has not shown any outward emotion from the so-far only encounter she's had with the couple, their constant jeering and insulting would likely make her mad as any other of the house guests.

Kasegi
When Kasegi forced himself into the house, and planned to record Papi laying her egg, Suu exposed him for the con man he was by broadcasting his thoughts with her feeler.

Ren Kunanzuki
Suu's only interaction with Ren was as one of Cerea's "tests" of the young girl's fortitude, reasoning that if she could not survive Suu's lewd "playing", then she would not be able to handle Rachnera.

Miia
Suu has not outwardly emoted towards the Lamia, though she agrees with Papi when the harpy claims that Rachnera is a better teacher than Miia.

Papi
While Miia and Centorea were initially hesitant about Suu, Papi befriended her immediately and the two share a sisterly bond. Papi was also the one who gave Suu her name in the first place and due to her strong maternal instinct, she is also very protective of the Slime girl.

Centorea Shianus
She and Centorea are on good terms but like the others, dislikes it when Suu molests her.

Meroune Lorelei
When Mero first met Suu, the slime made several attempts to suck on her slimy body, only to be stopped again and again by Kimihito.

Rachnera Arachnera
Suu and Rachnera have a hilarious relationship, as the slime's semi-liquid body renders her immune to any form of binding, thus whenever Rachnera attempts as such, Suu always turns the tables, and molests her in turn.

Lala
Suu first met Lala after subduing Rachnera's "session" with the headless Dullahan, then proceeded to engage her lewd "fun" with the lower half of the "agent of death." Also played monkey in the middle with Papi with Lala's head.

Doppel
Similar in species. Friendly or neutral since Doppel is friends with Kimihito.

Tionishia
Friendly or neutral since Tionisha is friends with Kimihito.

Zombina
When Papi and Suu were on a date with their master, Zombina watched out for them to find out the culprit.

After Suu ingested some toxins, she made a remark that Smith and the M.O.N. squad were freeloaders.

Manako
Friendly or neutral since Manako is friends with Kimihito.

Polt
In the anime OVA, Suu enjoyed the yoga session with Polt.

Kii
She considers Kii a friend, however she will molest her if given the chance as shown when picking out berries.

Draco
She dislikes her due to attempting to attack Kimihito, so she poisoned her and later molested her in retaliation.

Miia's Mother
Suu was thrown onto her.

Papi's Mother
Suu posed as Papi as a decoy, but as she then ran into Suu, Suu decided to wrap around her.

Centorea's Mother
An observant in the jousting match between Centorea and her mother.

Yukio
Met her in the interspecies friendly onsen. Suu was glad there was a bath suitable, but nothing else was noted.

Liz & Kinu
They considered Suu as a VIP or an important person, as Suu decides to ride on Kinu. Then Suu decides to put juice on her chest and molest her.

Potemkinme & Sebasstian
Ate all the food they made for Kimihito's friends.

Octo
When Suu took on a maternal personality by absorbing the seawater, she molested both Octo and Rachnera, which lead both of them to comment that Suu should not go into the ocean again.

Nega-Suu
Suu first met Nega-Suu in Chapter 52, and since she was a member of her species, she helped the larger Slime escape from the Black Lilies Laboratory tanker truck. A few days later, Nega-Suu telepathically contacted Suu to come to her with the hidden intention of absorbing the intelligent Slime girl. Either because Suu didn't know Nega-Suu's true intentions or because she thought in her childish naivety that the Black Slime would not harm her, she willingly went to the place where Nega-Suu would be waiting for her. However, the meeting was prevented by the intervention of the Black Lilies Lab staff.

Suu seemed to feel some kind of connection to Nega-Suu, but maybe that's just because they were both Slimes. However, after Nega-Suu also hurt Kimihito in their attempt to absorb Suu in Chapter 54, Suu's feelings turned to anger and she was willing to fight the Black Slime by any means necessary.
