He fought for me

Ethan had no idea what or why but he screamed like a teenage girl who just saw a cockroach in the bathroom. "KILL it! Kill it now!" 

The remaining insectoids and the two demons did not need to be told twice. They used this opportunity to pummel the bastard and be done with it once and for all.

Ethan's ragged breath filled the cavern as the hulking demon finally collapsed, its massive form crashing against the bloodstained stone with a resounding thud. The red glow of its berserk magic flickered, sputtering like a dying flame before vanishing completely.

It was over.

The cavern was eerily silent now, save for the exhausted panting of Ethan and his battered minions. The remaining insectoids twitched their mandibles, their bodies trembling from the exertion. His spiders, slimes, and demons stood motionless.
