The youngest of the Trinity siblings, Nena tends to present herself as cheerful and flirtatious when she is selfish and callous in the battlefield. A good example of her true nature occurs when she kills the entire Halevy family because she was frustrated that others were having fun while she felt overworked.
Such a scary girl with such a cute face. Better be careful when you see her in Winter Comiket! Thanks to Somiya for sending the photo!
