So that bag of shit manga called "In another world with my smartphone" could be a prequel to this? he eventually turned into a demon... It all makes sense, it's really really bad so it turned evil.
Jokes aside, this is awesome TOO awesome, I knew I didn't had to bother reading that bastard blabbering because our old man would expose him and give him a good beating!!!
I feel bad for Undine... Can someone save her? (or maybe she's free now) also the demon lord looks like a true monster!!! that's how it's supposed to be!
