She is
Hajime's childhood friend and fiancee who is a very high-class lady. At the same time, because she was raised in a rather sheltered environment, she barely has any common sense. These facts have led to Kureha being a very curious girl who enthusiastically jumps into everything that excites her. However, because she's been so spoiled since she was young, Kureha can't live without her butler
Angelina.
Her knowledge of sexual things is also very limited, as she believes that one could make a baby by kissing someone.
