Young girl Yamane Rin just finishes her training and officially becomes a cabin attendant at Fuji Airlines. On her first day, she thought it was gonna be a pleasant flight. Not so fast, girl. Apart from struggling to learn how to deal with difficult passengers, Rin meets the Chief Attendant, Hanazono Hinako, who appears to be a sweet girl. However, it is just one of her many sides. In fact, she's a dauntless bucchigiri girl who becomes a completely different person after work.

Note:
Bucchigiri means "winning (a race) by a wide margin" or #1, but it has other meanings. At one point, it was a degraded form of English's "break." These days, however, it describes an automobile's/motorcycle's extreme acceleration, which refers to delinquents.
