Yusei Oda

A spin-off based on the Saint Seiya series.

Sorata is an art instructor at Yamanoue School. At the young age of 20 he is already a full-fledged teacher with a meek and nerd-like disposition. Yet Sorata has a secret: he's Mouse, the internationally infamous thief.

Riki was a child when his parents died, leaving him hopeless and depressed. What saved him was a group of four kids calling themselves the Little Busters. They took Riki out and played with him during his time of need. He really enjoyed being together with them, and his grief gradually faded away. Now in his second year of high school they still hang out, fight and live together, and enjoy their school life.
