Cain Barzad

Cain (ケイン) is an alcoholic elderly man who lead the Deadly Sins to Byzel's annual fighting festival, which he also joined for an unknown reason.

Appearance
Cain is a short elderly man with combed hair, and a long mustache and beard. He also wears a clock, and his eyes seem to be always closed.

Ongoing Arc
Cain is first seen in Byzel when he drunkenly questions Meliodas and the others as to what they were looking for, since they didn't seem to be merchants. When the answer that the object is a weapon, he then leads them to Byzel's annual fighting tournament, whose reward includes the weapon they are seeking. Cain is then revealed to have also joined the tournament, an action he claims to have been in a "drunken spur of the moment", and to have survived the preliminaries, after which he is assigned to fight against King.

Later, after he enters the ring for his battle against King, he is shown to still be drunk, while the commentator speculates about the power the two fighters are hiding, having not participated actively during the preliminaries. Both of them are, however, revealed to be quite weak, much to the audience's disappointment, when King jogs toward Cain, intending to punch him in the face, but merely waves his hand in the air before he reaches his opponent, and Cain, as a response, readies a punch, but only knocks King in the head, an "attack", King comments, to have been very strong. When King then uses his ability, "Disaster", Cain, immediately alarmed, moves toward King with great speed and punches the Deadly Sin out of the ring, stating that he was so surprised that he lost control of himself.

Abilities/Equipment
During his battle with King, Cain initially appears to be very weak, but when King starts using his ability, displays great speed and strength compared to a normal human, moving toward the Deadly Sin in an instant and punching him out of the ring.
