EERIE QUEERIE! (Gosuto!), by Shuri Shiozu. First published in 1999 and first published in North America in 2004.
PLOT:
Mitsuo is a lonely kid with a strange gift: he can see ghosts. Because of this, he often finds him hassled by spirits desperate for attention and conversation. Sometimes they'll even go so far as to possess Mitsuo's body, as Mitsuo learns the hard way. When a dead schoolgirl does just this to confess to Mitsuo's classmate Hanasuma, he ends up gaining an unexpected partner who might be into Mitsuo more than he lets on.
