This is her level 8 Cosmosphere costume. It represents the true part of her self, her innocence when she was still a kid. This outfit is all white, and she has tied up her hair into twintails which makes her look more like her younger self. A part of the skirt section is slightly transparent, making her thighs visible. This outfit is mostly with bows and a bit of frill. She wears a white collar and white pumps with bows. This costume is very good costume, and a good choice for the final boss battle.
The level 9 Cosmosphere outfit, and the wedding outfit. This outfit is for the "special" ceremony that acts like a wedding, except no priest, but a mind guardian. This rather simple yet striking red and black dress would look like funeral attire if it were not for the large red roses used for decoration. Finally, she wears a pair of high-heeled ballerina type shoes.
An outfit that is designed for Dualstalls. She wears two short towels, one used to cover her lower part and the other draped around her shoulders and made to cover her breasts. She never wears it in her Cosmosphere nor in battles.
