An Angry Seraphim

"...If you guys sleep forever." 

Just as the guy did that, everyone went into a state of panic and put their guards up, ready to attack or defend while some tried to run away.

One person screamed on top of his lungs while running towards the exit:

"HOLY SHIT! ATTACK! ENE—"

BURST!

The council member's head burst open and he died on the spot.

The place where he just died, the red-haired guy appeared and said with a smile at his splattered organ,

"Did I say you could leave?"

Previously, his smile seemed bright to everyone, but now he appeared like a psychopath.

"Ruben, stop it." 

The light blue-haired guy who was silent all this while, said looking at the red-haired guy.

He then looked at the council members and said calmly, "there may have been some inconveniences, my apologies. Please settle down and ignore my colleague's mistake."

"Also, Ruben come back here."
