Harbinger in the Dungeon

"You can't be serious?" Nikolai was flustered.

He thought this would be a fun time with Kiro killing monsters, using them as a stepping stone to level up. It never crossed his mind that they could run into a harbinger of all monsters.

"I am." He answered exploding one of the monster's head with his bare hands.

Another troll came from the rear end attempting to avenge its comrade. If it was anyone else maybe they would've been caught off-guard but Kiro turned with one foot already in the air and connected his heel to its thick neck.

The head flew to the other side. Something that even the kicker didn't expect, which spoke on how strong he was and was vaguely aware.

"Oops!" He exclaimed.

Nikolai would've laughed if his hands weren't full. The hoard of them or the army as the system called it just kept coming.
