Riki is entrusted with finding the last member of the Little Busters to have a full baseball team of nine members. Riki hits a foul ball that consequently hits Mio, and he brings her a compress the next day. He notices that Mio always carries a parasol and that he always sees her reading under the same tree in the courtyard. She is known by other classmates as "shadow-less" because of the parasol and the fact that she does not have much presence. Using the same mentality of being helped by Kyousuke and the others during childhood, Riki asks Mio to join the Little Busters baseball team, only for her to decline the offer. After gym class, Yuiko enlists Riki to help find Mio's favorite book. Riki and Mio are unable to find it inside the classroom, thinking that someone may have hidden it as a joke. However, Yuiko arrives to explain that there was no wrongdoing, and Mio briefly meets Itō, the classmate who previously held onto her favorite book, revealed as a poetry collection. Kyousuke, Komari and Kudryavka summon Riki for baseball practice, and Mio goes to watch the Little Busters from the sidelines.
