Twigo

Twigo (ツイーゴ), also known as Lord Twigo, is a knight of the kingdom. He serves the Holy Knights and is revealed to be fairly heartless and does not care whether about whether his men are dead or alive.

Plot
Upon seeing Meliodas and Elizabeth, he quickly cut part of the cliff and they fell down. Then he realized that he haven't confirmed if they where the people in the report and said that are confirmed as 2 unknown dead people. Some of the knights said, that Alioni was under the cliff and that the thing he done is horrible, to which Twigo replied that they are 3 dead then and that it can easily become 7 dead. But for his surprise Meliodas jumped back from the cliff carrying everyone, including Alioni. That angered Twigo, since that changed his confirmed death toll. Although none of them looked like someone from the Seven Deadly Sins, he recognized Elizabeth as the kingdom's princess. Although there was a search order for bringing her alive, he said that an accidental death can happen, and while they where running, he swinged his sword to kill Meliodas and Elizabeth, cutting everything in it's path. She was saved by Meliodas, and moments later again was saved from another attack of Twigo, from which he cut the ground. Twigo went close to them and swing his sword again, thinking that this time he for sure would kill them, but instead he was the one that took his attack. Hearing Meliodas name, he realized who he is, but didn't wanted to believe and swinged his sword again towards him, but Meliodas again repelled his attack back sending him flying high in the sky and defeating Twigo.

Abilities/Equipment
Though not a Holy Knight, Twigo is still incredibly strong; managing to slice a large chunk out of a hillside with a single slash of his sword.
