Nitta Shinobu

She runs a restaurant on the ground floor of Shuuta's apartment building.
She also lives next door to him.
She often worries about Shuuta, who lives alone, but he finds that annoying.
She is technically enrolled in Hokumakidai University, which is right next to Hokumakidai Academy, but she's currently on leave.
Her sides are very ticklish.
