Nightmare Fetishist: Chitose likes to watch horror movies, and forces the others to watch with her. Judging by their reactions, the movies must be pretty gruesome.
No Social Skills: It's hinted that Chitose came from a small town with limited social interactions.
Tsundere: Even though she acts nice much of the time, she fails to admit her crush to herself or Ikkou, often harming him when others flirt with him.
Yuuko Atoda
A-Cup Angst: She tends to be jealous of girls that have big breasts compared to her own and angry with guys that prefer such girls.
Skinship Grope: Yuuko really likes to grope the other girls, especially Chitose and Sumi.
Friend to All Living Things: Her kindness extends even to animals, and this seems to be where her spiritual talents lie.
Nice Girl: Sumi is the only who one doesn't actively pick on Ikkou and tries to stand up for him.
Hinata Sugai
The Baby of the Bunch: She's the youngest of the cast, being the younger sister of Sakura.
Token Mini-Moe: Even though she is only a year or two younger than the other girls, she is notably undeveloped.
Sakura Sagai
Big Eater: She has the incredible ability to eat anything without ever feeling satisfied and without changing her appearance. Somewhat expected as she represents the realm of the Hungry Ghosts.
