Yoshiharu Hisomu

Appearance
(日染 芳春 Hisomu Yoshiharu) Is a handsome yet pain-loving, masochistic teen. He has mid-length, heavily layered purple taupe hair with grey highlights. His eyes are of a golden olive color, and he has multiple piercings on both ears and a single snake bite piercing below his lip. He is constantly seen with bandages covering both his neck and wrists. Yoshiharu's clothes always look quite worn down and are paired with flip flops.

Personality
Hisomu has been described as a person who does things that other people deem wrong. These actions bring him immense happiness. He absolutely needs to be kinkshamed and is apparently really blunt about everything. His sin is "The Immoral".

Relationships
Agata Katsuhira- Hisomu took a liking to Katsuhira the moment their eyes met in Episode 3. This is further backed up in Episode 4 where Hisomu says that he was especially pleased to meet Katsuhira. He was at first only willing to talk to Katsuhira out of all the Kiznaivers, even though he asked Katsuhira if he could die for him back when they met. Katsuhira also caused Hisomu to bliss out in pain after Katsuhira jumps off a bridge into oncoming traffic. Also, in Episode 5 Hisomu was trying to hurt Katsuhira purposely by asking To hold the firewood while he was chopping it. It may appear that he is trying to hurt him (or possibly other Kiznaivers) in order to share their pain, rather than doing any harm to himself. It is also shown that Katsuhira doesn't care about Hisomu's masochistic personality as they do interact more in Episode 4 and 5 and Katsuhira appears to have nothing against him.

Nico Niyama- These two seem like they are friends. Even though in Episode 3 Nico calls Hisomu 'hot', she appears to have no intention of trying to get together with him. In Episode 4 they are shown to walk to the training camp together.
