Reborn!: The Good-for-Nothing Saves the World

As Good-for-Nothing Tsuna's shadow, Sawada Kuroya is known as Good-for-Nothing Too.

They look exactly alike, and their good-for-nothing tendencies are just as impressive. Failing exams, tripping on flat ground, getting stuck on the pommel horse... All in a day's work.

When Sawada Kuroya was mistaken for Good-for-Nothing Tsuna yet again and beaten to a pulp by an enemy, the bruised and battered boy spat up blood. "Please, just get a pair of glasses."

Then a man named Shirogane arrived, and Sawada Kuroya, a total weakling, gained immense power. He became the Tenth Shadow King!

Facing the menacing Spider Boss, Sawada Kuroya gave a wicked smile. "You think you can mess with me? You?"

Screw you. Get lost!

Theme: Never underestimate a good-for-nothing. They're all stocks with potential.
