Tsundere: Type B. She's nice most of the time, but she usually shows her aggressive side to Sanpeita, whom she's been crushing on since they were little.
Only Sane Man: Next to Sanpeita, Izumi may be one of the few sane people in the world.
The Friend Nobody Likes: Her openly perverted nature tends to make anyone around her uncomfortable, not that she cares. The only one who hangs out with her is Izumi.
Lovable Sex Maniac: Downplayed. She's not shy about showing her pervy side, but it creeps most people out.
