After a Plane Crash, I Was Reincarnated as a Demon King in Another World, Struggling to Survive.

Kids, I crashed and killed a man with horns, so I became the [Devil King]. There are many beautiful girls in the demon clan, yes, that's right, I am the demon king. No, no, why don't I have any magic power? What does it mean to ask the Demon King to take action when the demon clan is in danger? … Fafnir prayed to heaven, and the only answer he received was the technology from Energy City on the crashed plane. Hey, can we reconcile? Facing the human expeditionary force, Fafnir had no choice but to turn on the emperor's engine. Don't underestimate my god-level weirdo-level acting skills!
