Mitsuki (EntityTopic, 18)
From Compile Worlds
Witch is a blond witch who hails from the Puyo Puyo series (The Madou games, to be exact, and all of them, no less). She's notable for being a witch dressed from head to toe in blue (Except in YON, where it's obvious she's not a newfag) and being a happy young teen witch who speaks in a relaxed and immature way. She's also obsessed with blueberry muffins and marshmallows, moreso the latter, and would do them any time given the opportunity.
Anyway, she's apparently a friend of Arle's and Schezo's who sometimes tags along with them in their own little adventures 2/2Puyo Puyo~nThe Tower of the Magician (Though, it's probably her own way of making up for accidentally sleeping with the former and being a pervert in front of the latter). She's even had her own adventure where she dreams (and really does) got her powers and met her own version of Doppelganger Arle. Oh, yeah. And she's known to have a grandmother named Wish, too.
She, like Harpy, has had her sizable fanbase utterly ignored by SEGA, being entirely absent in PP15th and being reduced to nothing but a cameo appearance as another participant in Draco's beauty contest. Needless to say, much shock and disappointment ensued.
