Chizuru Aizawa


One of Chika's good friends in high school, who took swimming lessons from Tina along with her schoolmates. She's very afraid of the water, but managed to overcome her fear and learned how to swim. She is the shy one of Chika's group, often overwhelmed by adult matters (of the trio, her mind is the most prone to perverted thoughts) and prone to constant blushing and the occasional fainting fit.
