篠原 小唄

A petite-figured older sister who takes care of her younger siblings in place of her parents, who are busy taking care of their Izakaya.

Despite being the same age as the protagonist, she has acquired a maternal nature due to being an older sister. She doesn't have an inferiority complex because of her childish appearance, but she does think that she's not ready for love. She doesn't have much sexual knowledge, but she is very serious and studies hard once she starts dating the protagonist. She doesn't realize that she has a dormant desire to be pampered by someone.
