Suzuki Eri

Alto-kun's older sister. Teacher at Saint Mirowa Academy. 26 years old. She's easygoing, kind, and dependable, but also a bit slow-paced and airheaded. The big sister who's watched over the trio of childhood friends: Alto, Kurumi, and Mirai.

She speaks formally even to her much younger brother, Alto-kun. A soothing older sister who'd rank high on any list of ideal marriage candidates.
Though kind-hearted, when she gets angry, she says harsh things with a smile and in her usual tone—which can be scary or make your heart flutter... Since her parents are overseas, she acts as a surrogate parent to Alto-kun.


So big you'd want to suckle after shouting, “Blood ties don't matter, Eri-nee!!”
