It's Annoying Because My Childhood Friend Is an Archmage

My childhood friend is an archmage, one that cannot control his powerful mana and occasionally goes on a wild rampage. "Skyla, would you like to have the empire for your birthday? I'll make you the emperor!" To be more precise, he is an archmage with no common sense and morals. Once again, I'm still struggling to keep him from destroying the empire today.

...Life is very hard.
