Biography
Hisashi was an acting teacher who lusted after his young, female students. Eventually, he would find himself smitten by Niina Sugawara and when she became his student, one of the first things that he did to her was caress her leg in a sexual manner.

From there, Hisashi had taken to psychologically manipulate Niina for the duration of their time together to the point that Niina felt that she was in love with him and when she was 14 years old, she pops the bubble and asks him to have sex with her. For pragmatic reasons, he does not. This would lead to Niina developing into an emotionally unstable teenager who had an odd sense of perceiving things.

In the main story, Hisashi is introduced performing the same psychological manipulations on another young girl, telling her that she bored him. Niina gradually returns to him to ask advice as she was unable to comprehend her feelings. She also kisses him on the lips as a means of invoking some response only to be disappointed that it felt hollow. Hisashi then conducts further mind games on her, coercing her to go after Izumi Norimoto despite knowing that her best friend Kazusa Onodera had a crush on him and he had just confessed to her.

Despite flinging herself onto Izumi while they were in a public bus, Izumi rejects her. This causes Niina to become further confused by these developments, Niina decides to consummate her relationship with her former acting teacher.

She places her leg on his lap, and he starts to gradually lick his way across her exposed belly. Just before it segued further, something snaps inside of Niina, her now realizing that everything that Hisashi had done to her was wrong. In an act of impulse, Niina punches Hisashi squarely in the face, shattering his glasses upon impact. Surprised, Niina frantically apologizes and leaves the room. After that, Hisashi does not resurface in episode 12 of the anime most likely indicating that he continued to psychologically manipulate and molest his other students without issue.

Trivia

 * Fans of the show gave Hisashi the nickname "Pedo Steve Jobs" due to his uncanny resemblance to the late Apple founder.
