Masahiko Katou

Masahiko Katou is the half brother of Jeri.

He actually appears only once, when he was playing with Calumon, but this fell down and hurt.

His mother but was equivalent to and comforted him.

The false Jeri, so the D-Reaper-agent, stood by and watched Calumon. Masahiko actually has a good relationship play Jeri and loves it with her and her hand puppet too.
