Rainier is a character from Disgaea D2: A Brighter Darkness. She appears to be a long-haired and busty Sea Angel and is a member of the Krichevskoy Faction, having been Laharl's babysitter. It is also implied that her tendency to smother Laharl in her breasts played a part in his fear of busty women. After defeating Darkdeath Evilman she will join your party as Etna's vassel at level 1200.
