From Viz:
Chuta Kokonose is like any other middle school student. He's easily distracted, says things he shouldn't say out loud and accidentally creeped out the prettiest girl in his class--and all of his problems could be avoided if it weren't for the mysterious voice in his head. One day, Inspector Chips of the space police élDLIVE appears in his locker and seeks to recruit him.
But first, he'll have to pass their entrance test: apprehending a notorious space criminal.
