Hana to Alice: Satsujin Jiken

Arisugawa Tetsuko has just moved to a new house with her recently divorced mother.

She becomes a transfer student at a school where a strange rumour lingers among the students.

When she starts to investigate into it, she ends up meeting Arai Hana, her young strange neighbour who rarely leaves the house.
