Yumeko Culus was a friend of Ami Kirio at a school called the Garden of Delinquents. Yumeko has light blue hair and light purple eyes. She wears a white shirt with a blue bow, blue shirt, and white long socks. She also wears her good luck charm on her left ear. Yumeko was a happy girl. Unlike most of the students at the Garden, she was very kind to Kirio and enjoyed spending time and hanging around with him. Unfortunately, she fell into despair when Kirio attempted to catch her good luck charm, letting his guard down when one bully threw it into the river.
