笹ヶ瀬薫

Kazuki's classmate, she's the athlete of the group. Kaoru is the school swim team ace who competes at national level. While at first look she seems to be the cool beauty type, she’s actually quite the trouble maker type and pranks Natsumi all the time. She can be described as being short-tempered and frank, who's rather boyish both inside and outside. Due to all that she is quite popular as a net-idol celebrity.
She has an awesome petrobot called Ni-gi.
