The character you are referring to represents the human realm and has a crush on ikkou, but constantly denies it. despite appearing friendly most of the time, she struggles to admit her feelings to herself or others, often causing harm to ikkou when other characters flirt with him. she is known as a stereotypical tsundere who frequently puts ikkou down without provocation and claims to have no hobbies initially, although enjoys horror films. this character is frequently harassed by yuuko for her large cup size, perhaps more than the others. in early episodes, there is a running gag about where she used to live, with one clue being that all of the town's businesses are located in a small two-story building.
