4

Riki helps Kudryavka Noumi move boxes into her dorm, then visits the roof to thank Komari for caring for an injured cat. He discovers her asleep and hears her mention a brother, though she claims to be an only child who dreams of a sibling reading a book about eggs. Later, Komari finds a picture book with Takuya Kamikita’s name on the back but lacks memories of him. She asks Riki and Rin to visit a retirement home with her, joined by the Little Busters. While there, Riki cleans the room of Kojirō, an elderly man who usually frightens visitors. After Kojirō drives Komari away, he reveals his full name is Kojirō Kamikita and warns Riki to keep her distant.
