Yoshiharu Hisomu

Yoshiharu Hisomu (Japanese: 日染芳春, Romanized: Hisomu Yoshiharu) is a main character and one of the group of seven kiznaivers in the titular anime, manga, and novel series Kiznaiver. His identification when he experiences pain is D-7.

He resembles the sin of Lust. His modern-day sin is 'The Immoral' (Japanese: インモラル, Romanized: Inmoraru).

He is voiced in Japanese by Koutarou Nishiyama and Hans Wackershauser.

Appearance
Hisomu is a naturally handsome, yet unkempt, teenager. He has mid-length, choppy 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 labret piercing beneath his lower lip. He is perpetually seen with bandages covering his neck and his wrists. His clothes always look quite worn down and tattered, and are invariably paired with flip flops. He appears to stand around 180 cm (5 feet, 10 inches) tall.

Several characters point out that Hisomu is a "natural hot guy" (in constrast with Tsuguhito Yuta, who had to work hard to achieve and maintain his current appearance). Despite his ratty look and lack of concern for personal care, he is often checked out when he is walking in the street, or on the rare occasions that he comes to class.

Personality
Hisomu is portrayed as an eccentric masochist throughout the entire series. As a masochist, he experiences arousal when experiencing, or even thinking about pain, and typically expresses this arousal quite vocally and without shame. This causes much chagrin among the kiznaivers, especially Yuta who is deeply peeved and put off by the unsuitable behavior. On top of that it is very ironic, since Hisomu is wired to enjoy an experiment that most people would find difficult to endure.

There is subtle implication that he is suicidal, though like the rest of his traits, he likely does not view it as a problem to concern himself with.

When he is in the same vicinity as Nico Niiyama he will occasionally act childish, as their respective outlandish personalities seem to amplify each other's. He states to Hajime Tenga that he cannot swim and that he doesn't wish to drown, which contrasts his usual all-inclusive attitude towards pain and suggests that drowning is one of the few forms of pain he doesn't wish to endure. It is unclear whether he has a trauma related to this or anything else, because he seems to have decidedly pushed everything except pain out of his mind.

Aside from this, not much is known about him in general, and he is considered an enigma by everyone, even the Kizna Committee members who watch his every move. Although he seems benign and spends most of his time smiling innocently, he is capable at all times of being blunt or ruthless with his words, which unnerves the other kiznaivers of his group.
