Еґава Кусумі

Kusumi was born and raised in Yurigaoka, but she lost the trust of everyone because of an incident that occurred in middle school. In particular, she is afraid to talk to people because of circumstances involving her best friend, Ichi Tanaka. She is a girl of few words and often spends time alone, but her combat abilities have been revered as one of the best since the construction of Yurigaoka, enough to earn her the nickname "Child of God". Supported by Shiori Rokkaku and Soraha Amano. Her specialty is housework and her cooking is comparable to that of a chef."
