kunou

Kunou acts like a princess and responsible co-leader despite her young age. However, she still has a childish side to her. She tends to smile in amusement when she sees something interesting and things new to her sight as it seen when she is amazed by Issei's Scale Mail armor. Also, as noted by Yasaka, Kunou can also be obsessive, as seen when she protested against her mother flirting with Issei.
