Starting Today, I'll Destroy the World

Another world = hero = respected by all = surrounded by beautiful girls?

No, no, no. Another world = demon king = hated by everyone = scorned by beautiful girls.

Why isn't my transmigration like everyone else's!

If demon kings have a bad reputation, then I'll try to change it! Time for a journey to spread love throughout the world!

Why... isn't anything going the way I thought it would?!
