Hua Zijun, a former student of Seagull College, is an eccentric shota with a transparent body, accompanied by two jack-o'-lanterns (white staff generation), with a white face and a red "seal" on the left, an old school uniform and a kitchen knife as weapons. It is the seventh "flower in the toilet" in the seven incredible campuses.

Having the ability to realize other people's wishes, it is widely rumored on campus that there is a third ladies' room on the third floor of the old teaching building, and Hanako is there. He will satisfy the wishes of visitors, but it is said that he will take something important as a reward.

In fact, according to the actual situation of the parties, different suggestions and guidelines will be put forward to realize their wishes, instead of rashly giving them the power to go beyond the laws of nature, because the higher the scope and difficulty of what the parties want, the greater the price they need to pay.

It is the seventh of the seven wonders-Hanako in the toilet, the third generation and the first of the seven wonders. Unlike Hanako in the past, Hanako in this story is a boy. Ningning called him "Huazijun", an eccentric disciplinary committee member who has the responsibility to maintain the stability of the relationship between human beings and eccentricities.
