Tsukasa and Amane are identical twins, they were very close as children, but their relationship began to deteriorate after an event - it was on their fourth birthday, when Tsukasa disappeared for half a year and miraculously returned, but after that their life went downhill.

The brothers growing up together and everything seemed normal, but their mother became abusive towards Tsukasa and the father ignored the problems, often absent from home. Amane was defended his brother, but the whole unsettled situation in the house affected him. He gave up on his dreams and one summer night,at the age of 13, he murdered Tsukasa with a knife for an unknown reason and then committed suicide.

Now they are ghosts haunting Kamome Academy. Hanako hasn't been seen his brother in a long time, but his loneliness was over when he found friends, although unfortunately, Yashiro is destined to die soon.

Tsukasa, Hanako's yorishiro,he has escaped from Hanako's boundary and, with the help of his assistants, was carrying out a plan to destroy all the yorishiros of School Wonders' in order to fulfill Sakura's wish and for Amane to receive a wish from "God". Tsukasa did controversial and cruel things to achieve his goal.

Hanako made a lot of cruel and wrong decisions in an attempt to save Yashiro - in collusion with his brother, he destroyed yorishiros, upsetting the balance in the school, which led to the penetration of more supernatural things into their world, and then arranged everything so that the separation of the worlds occurred and Nene's friend had to be sacrificed for her life. But now Hanako has to figure out how to do things right.

It's another day of one of them.
