Chitose Ikeda

A 14-year-old second-year middle school student with a twin sister named Chizuru. She has semi-short hair that is a purplish white color. Originally from the Kansai region, she speaks in a Kansai dialect. Generally, she has a calm personality, but she actually harbors intense yuri delusions. Her main focus is the coupling of Ayano and Kyōko. She takes off her glasses to block her vision and concentrate her nerves, entering into full-blown fantasies. During her fantasies, she gets nosebleeds so severe that when she tries to stop them by pinching her nose, the blood comes out of her eyes, sometimes causing her to faint.

She is Ayano's best friend and reached out to Ayano, who was alone when she first enrolled at Nanamori Middle School, becoming her friend. She seems to see through Ayano's feelings for Kyōko, subtly interjecting comments and supporting her, who tends to keep things to herself. She also gets along well with Kyōko, who tends to cause trouble and inconvenience to those around her. She is academically gifted, ranking within the top ten of her grade on midterms.

She has a low tolerance for alcohol and got drunk from the alcohol-filled chocolates brought by Kyōko. When drunk, she becomes a kissing fiend, kissing anyone in reach.
