小森江 すず

Sousuke's "former" younger (real) sister who he grew up with during his early childhood days.

Suzu is in her first year, just like Nanaru, and even winds up in her class when she transfers. She's a very devoted sister, who's never stopped loving her brother even after they were seperated during early childhood. She's very docile (much unlike Nanaru), as well as gentle and affectionate. She can be a little bit of an airhead, but she's a great sister, both in terms of looks and brains.
