Kiyonori Taishi is a selectable colleague in After School Affairs. He's the Japanese History teacher from Seika Ladies Academy and now Seishun High School.


Kiyonori had a lonely childhood for his parents were teachers and always never home. He started reading Japanese history books to replace the longing for his parents which is how his passion for history began. By the time he was in elementary school, he was already a history geek and would continue to read about history instead of playing with other children.

Sometime later, a girl confessed to him that she was in love him. He didn't understand why she would love someone who has never interacted with others, but he went out with her. He was happy but then shortly found out that she only went out with him for a bet, and broke up with him because he was a history geek. Since then, he'd stopped caring about everything (except history) and closed his heart from everyone.

He wanted to be a museum curator, but his parents were against it and wanted him to be a teacher since that was their profession and that museum curators don't make a very good income. Kiyonori complied and became a teacher, and worked at Seika Ladies Academy, but still researched on becoming a curator. Despite being an expert in Japanese History, he cares very little for his students since they don't show an interest in history.

He showed very little interest in the schools merging, and was discouraged that he would have to be partnered up with a teacher from the other school. That teacher turned out to be you and unbeknownst to him, you would be the black ship that would open his heart.

  • Teacher Attire: Kiyonori wears a grayish pinstripe shirt, with a blue blazer, olive green pants, and black oxford shoes.

  • Home Attire: Kiyonori wears a dark gray loose sweater with a light gray horizontal stripe, and grayish pants.


Kiyonori is generally very quiet and doesn't like to socialize with other people, he'll mainly get out of any social event if he can. He’s quite apathetic on whatever doesn’t interest him and as a teacher, he cares very little about his students or about the no-dating rule.

He's extremely passionate about Japanese history to where he'll be extremely talkative, as opposed to being naturally reserved, and explain the history of something, like the tradition of giving soba noodles to neighbors when someone moves in. While many people get turned off by this, he can draw in people with his lectures because he's so passionate.
