Koyuki is a normal high school kid with a big problem: he can't stop himself from screaming at his crazy friends.

Koyuki tries to escape from his crazy friends by playing Commoner's Village, his favorite video game; but it doesn't work, and his friends follow him into the world of the game.

Koyuki's worried about his future; he wants to be a teacher, but he's not sure he can do it.

The whole class has gone on a field trip to an amusement park; Koyuki wants to go after his love, but his crazy friends are standing in his way.

Koyuki was so mad he walked in front of a truck, and now he's dead.

A new friend has come, and he's just as nuts as the rest; a samurai who wants Koyuki to punish him.
