Little Busters! S01 E10 The Blue of the Sky, the Blue of the Sea

While searching for a stray ball sent flying at a Little Busters practice, Riki encounters Mio, a girl who always sits and reads in the shade of a tree with a parasol open. There's one book she's particularly fond of, but she won't tell Riki what it's about. When she loses the book, it's up to Riki to help her find it.
