Masochistic Young Buds Episode 3

Mariya lends Kanako his rosary which is of great value. Unfortunately, she leaves the rosary in the classroom. As she went back to get it, three girls, who are fans of Ryuuken and are jealous of Kanako because she is on good terms with her, found it and threw it out of the window. Kanako runs outside to search for the lost rosary. On the same day, Ryuuken tells her that she will protect her.
