A humanoid demon with lumpy wrinkled skin. His face resembled a cicada's mouthpiece with small sunken eyes beneath a heavy brow.
Trolief was known to be capable of flight, though any other abilities are unknown.
After Zennon had announced the forthcoming demon invasion across the world, it took only five minuets for a swarm of devils to begin descending down upon the cities of the world, killing and destroying all they could. Among these devils was Trolief, who joined in among the apocalyptic chaos that engulfed the world.
Trolief was among the group of demons that surround Akira Fudo after he was knocked out by Psycho Jenny. He argued with the others over who got the right to kill him, but their arguments were stopped when General Zann came to ground and silenced the devils squabbles, telling them that Fudo was under the protection of none other than Satan.
