The Leader of the Ten Commandments

Bellion

Gloxinia: Hey Yoshirito, are you even a demon at all? You look like you're just a normal humanoid samurai. Seems unusual that you would be training in purgatory.

Yoshirito: I'm a special type of demon that has a characteristic of a goddess and a demon. I could use Ark on any race and it'll kill them instantly. I don't use my magical power, but if I have to use it to protect people that I love, I'll use my magical power.

Estarossa: What are you guys babbling about? There was a large surge of power sensed by Meliodas and Zeldris at the castle of Camelot. It's a group made up about 6 people. It's like they have all a combined combat classes of 234,571.

Demon King: Those six people are the 2nd most powerful group of elite demons in the whole demon realm. They ste called the six knights of black, they are led by Bellion, someone that I rejected from going into the ten commandments.

Meliodas: Father, didn't Pump tell you a couple days ago through telekinesis, that Bellion was gonna destroy the castle of Camelot. Pump warned Bellion not to destroy it or he will burn in the deepest part of Purgatory.

-Timeskip to Camelot-

Meliodas: He only destroyed a part of the castle, but I will tell the demon king at once because I can fight him for destroying part of the castle.
