Rapdevil

"Hey friend... Have you ever seen The Devil? I will show you."

-Rapdevil to Horyang

Rapdevil was a Regular nicknamed "Devil of the right hand" because of his ability to transform his right arm into a black and blue striped 'power mode.' He had been hired to travel with a rich company owner's son. He claimed to have defeated Hatsu, who apparently is now an incredibly powerful and well known swordsman in The Tower.

He achieved the 4th seating in the World's Strongest Regular Test with 11,988 points, however died during the next test, the Untrustworthy Room Test, killed by an unknown assailant.
