Rinnew

Information
She became Mikan's Dungeon Master after the God of Darkness rewarded every winning Dungeon Core. Mikan asked for a capable Dungeon Master like Keima, so the Dark God fiddled with fate a little. Mikan registered Rinnew as her dungeon master during Keima and Aidy's sight seeing tour of Rabbit Paradise.

Appearance
An intimidating-looking woman.
