takamiya mana
She is a character from Date a Live series, and is Itsuka Shidou's biological little sister. She is a temporary Second Lieutenant of the AST, and she used to work for the DEM Industries base in England as a Wizard.
Mana appears to be around the age of a middle-school girl. She has long blue hair, tied up in a ponytail, with some bangs left out. She has brown eyes and a mole under her left eye. She resembles Shido a lot, as stated by Tohka.
When she is at the JGSDF base, she wears a military uniform. Due to her young age, however, it gives others the impression that she's cosplaying.
During combat, she wears a light blue CR-Unit. After joining Ratatoskr, she wears a black and blue CR-Unit vaguely resembling a wolf's fangs and claws.
