Masahiko Katou

Masahiko Katou is the half brother of Jeri.

History
Masahiko actually appears only once, when he was playing with Calumon. Unfortunately he fell down and cried until his mother came to comfort him. Meanwhile false Jeri, D-Reaper-agent, stood by and watched Calumon. He was hurt and confused when the false Jeri walked over to him and proceeded to pin him down to the floor with an evil look on her face stating "All suffering must be eliminated."

Masahiko actually has a good relationship with Jeri. He often plays with her and loves it when she uses her dog hand puppet.
