Tetsuko "Alice" Arisugawa has just moved to a new house with her recently divorced mother and enrolled at a school where a strange rumor lingers among the students about "Judas," who is said to have been murdered over a year before. She is told that if anybody knows his fate it would be Hana Arai, the recluse in the house next door who has been unable to bring herself to attend class since "Judas" disappeared.
