To Make a Happy, Sunny Place.Riki helps his classmate Kudryavka Noumi carry her boxes into her new dorm room one afternoon. The next day, Riki goes to the school roof to thank Komari in place of Rin for taking care of Fabre, a cat that was injured. However, Riki overhears Komari sleep-talking about her brother. When she wakes up, she admits that she is an only child and that her brother only appears in her dreams to read her a picture book about an egg and a chick. The following day, Riki and Rin go to the school roof, only to find Komari a little sad. She found the picture book from her dreams in the storage room. Based on the name Takuya Kamikita on the back cover, Komari suspects that her brother was the author, but she cannot remember anything about him. Riki and Rin accompany Komari to a nursing home, and the other members of the Little Busters decide to tag along to volunteer. Riki enters the room of a loud and grumpy old man, cleaning the room regardless. After the old man scares away Komari, he reveals himself as Kojirō Kamikita and tells Riki to never bring her near him again.
