King of Rejects

The demon king died 20 years ago. What does that mean? Global war of course! Did you just become an Assimilator? Congrats! Off to the battlefield with you! Wait, you're not even a grown up? Too bad!
Your ability isn't good enough? Guess a life of mining will suit you!

Calling them 'dangers to society', you threw them out. Guess we'll have to make a better one ourselves. Or should we just take it all back? Hohoho, so many fun options!

Surely, this'll all work out. In perfectly normal and human ways.
