Renten

A fantasy princess, serving under her master, Barrows.

She has very small wings (about 5cm) on her back (well, more on her waist.) She can fly by flapping her wings. (Even when she has clothes on, her wings are still out.)

Underneath her eyepatch, she has a blue crystal embedded in that eye. Why the crystal is there, she has no idea. But the crystal has a powerful magic energy, that tries to absorb Mikoto's vitality.

The ratty plush bear she's always carrying can be used for mind control.
