Shikii no Juunin

Middle-school student Chiaki Honda neglects his studies, smokes, and wears his hair dyed bright green. One evening at an arcade, a girl challenges him to a match and introduces herself as Nanako Kikuchi. She proposes a wager: her body against Chiaki’s watch. Chiaki loses decisively and goes home angry. The next day, Chiaki encounters a strange young man on the train who looks remarkably like him. His life continues, and before long, he runs into Nanako again.
