Paččigi!

Romeo, A.K.A. Kosuke Matsuyama, is a second-year high school student. A nice, normal, nonviolent type, he suddenly finds himself in the middle of a rampaging crowd of Korean boys, outraged by insults perpetrated by several of his idiotic class-mates on two Korean girls. He makes a narrow escape, but soon after, he and his best bud Yoshio are sent by their home-room teacher to invite the Korean students to a friendly soccer game as a way of restoring the peace.
