She's one of the main female lead and she is also known for her temper and tendency to punish main protagonist, Keitaro Urashima, by physical violence, she is the first female character introduced in the series who was trying to pass the University of Tokyo entrance exams. Despite her anger towards Keitaro, she is reliable and responsible for her actions, willingly to take care of herself. During the story events, she is the one who gets caught by Keitaro's clumsiness from seeing her naked to tripping on top of her chest or lying in very suggestive positions, she is also the one who usually attacks him when he is in this situation with other girls despite that fact, if it isn't his fault. To me, she's like every other tsundere who despise the main male lead on the outside but sweet in the inside. This is only on the first eight episodes of the anime TV series.
