Kick no Oneesan

Shinichirou Akiyama is an ordinary office worker and a devoted fan of Hana Natsuno, a talented female kickboxer. When Hana suddenly disappears from the competitive circuit, Shinichirou is left wondering what happened to the fighter he admired. He later encounters her completely drunk on the street, beginning an unexpected connection between a serious salaryman and a gifted athlete whose life outside the ring is far messier than her public image suggests.
