Jigokudou Reikai Tsuushin

Tetsushi is a fifth-grade delinquent who dominates the students at Jouin elementary. He teams up with Ryuuchin, and Tsuda, who occasionally joins them. The trio is feared in the town as the "three evil prankster kings." During a visit to a remote, eerie pharmacy, they encounter an elderly man who grants them an unusual and supernatural ability. Shortly after, they begin confronting various ghosts and demons.
