[1] A pharmacist, police officer, and a janitor are commuting fall hostages on bus that gets hijacked by a terrorist.

The terrorist forces the three into a violent game of Rock, Paper, Scissors and Russian roulette, which the janitor Testsu loses.

After noticing that pharmacist Saki has only one eye, the terrorist feels remorse and finally turns the weapon on himself.

After being humiliated in the police force, and saving Tetsu from the yakuza, the two decide to get revenge on society by starting a revenge-for-hire operation.

By scribbling graffiti on bathroom walls to advertise their business, Shingo and Tetsu offer their services to anyone with a problem.
