Voiced by: Aoyama Yukari (VN), Tomonaga Akane (Anime)

Second daughter of the Kawakami family, and Yamato's classmate. Kazuko is known for her cheerful demeanor and never-give-up attitude despite being known as a crybaby when she was younger. She is an orphan and was adopted by an old lady in her youth. However, the foster mother died and Wanko was adopted by the Kawakami family at Momoyo's request. Since then, she has grown to love her new family, especially Momoyo and hardly considers finding her real parents as a result.

She is always training and always looking for a good fight in order to become both a suitable opponent for Momoyo and also a training assistant at the Kawakami temple. She is the target of admiration and affection from both Kuki Hideo and Minamoto Tadakatsu, the latter of whom, she knows from the orphanage and also live in the Shimazu dorm with members of the Kazama family.

She uses a spear with her unquestionable speed and has developed a rivalry with Chris.

She is nicknamed "Wanko" due to having dog like tendencies, such as responding to a whistle that each member of the Kazama family uses in order to call her.

She is capable of studying harder than she exercises once she gets started, but due to her interests in being a training assistant, she hardly does so.
