King is the S-Class Rank 7 professional hero for the Hero Association. In truth however, he is just a normal average person, who unintentionally gained credit for things he hasn't done. King is noted to be clever and a cheat. However, he is not a bad person or truly selfish, he just couldn't bring himself to tell the truth to people. Even though King is just a average human, he has a power of luck that everytime he ends up in a bad situation, he always survives it accidently.
