Takahito Harada's mascot girl Pleinair, she has made appearences in many other games rather than Disgaea but in the Disgaea games so far she was a Dark assembly attendent, a news cast lady, and a school attendent.

The other one of Takahito Harada's creations is Asagi which was generally suppose to be the main character of a NISamerica game but the idea was scrapped so now shes more of a secret character trying to become the main character of a game
