Yumiko is a cool 1st year, daughter of Yoshiko (Yohane) Tsushima and Hanamaru Kunikida. Yumiko is a closeted "little demon" character, hidden by her love for books. She is generalized as a loud, funny girl, everyone loves to be around her. But her (non-blood-related) cousins--Marina, Kiyuna, and Hikari--know that she is more than a little crazy behind closed doors. The group "Mom Squad" is generally afraid of her when she is with Hikari and Nachiko. A note: her voice should be a bit high, and sound in a way like Nico and Yoshiko's voice.
