Koneko Toujou

Due to witnessing her sister supposedly losing control over her nekomata power and killing her master, Koneko became traumatized by the event, causing her to become withdrawn into herself and stripping her of most of her emotions. As a result, Koneko originally had a quiet and cold personality, rarely showing any feelings or emotions, even when she was speaking. It is noted that her serious personality is a result of receiving influence from Rias, and it is also antithetical to her sister's mischievous and outgoing personality. She was also the only one in the group who did not initially get along with Issei, often insulting and rebuking the latter for his perverted nature, although she reveals that she respects him for never giving up and considers him a hard worker.

Koneko is a petite girl with white hair and gold eyes. Her body measurements are [B67-W57-H73 cm] [B26-W22-H29 in]. Her weight is [31 kg] [68 lbs]. The front of her hair has two long bangs going past her shoulders and several loose bangs hanging over her forehead, while the back has a short bob cut. She also wears a black cat-shaped hair clip on both sides of her hair, one of which contained the data on artificially making new Super Devils.
