Awesome, guess Zeref didn't put up much effort in writing them to be very powerful before manifesting in form. lol. I once chilled the fact that the Nine Demon Gates are Demons of the Book Zeref until Silver's revealed to be an undead chills me but now with the debut of the Demon Clan, now they're terrifying than the NDG even their appearances scare me.

Anyways, I'm rooting to see what the Demon Clan can do in battle and Escanor is going to make his debut Jan 28. rumored to be a vampire (not Twilight vampire, but a Dracula Untold or Abraham Lincoln The Vampire Hunter vampire)

Nine Demon Clan members (hopefully their names will be revealed and might be badass in future chapters):
 * A spiky black-haired Meliodas-lookalike kid with a Black Mark.
 * A tall armored figure with a helm similar to Golgius of Weird Fangs and has a spear/scythe hybrid staff.
 * A little girl with lots of tentacles coated with black matter at its tips around her.
 * A female tomboy version of Meliodas whose only clothing is the black matter half her body.
 * A four-armed humanoid behemoth whose face covered by a cloth.
 * A man who somewhat resembles Meliodas' wanted poster.
 * A French-man with a rapier.
 * A cloud of dark matter with numerous face masks.
 * A teenage girl with dark matter around her body who looks like the oneshot version of Elizabeth.
