Hanada Shounen-shi

 Young Ichirou Hanada lives with his parents and grandfather in a quiet rural town. He is a little brat who constantly teases his sister, insults his mother, fights with everybody, and eats a lot.

Ichirou has a near-death experience when he is hit by a truck, and when he wakes up he can see and talk to spirits. The spirits of people who have just died but who cannot pass on yet seek him out. They have some unresolved issue in their lives that is holding them back, and Ichiro must help them out.
