I Summoned a Max Level Demon by Myself

I woke up and found myself in a game.
I even became the boy who was supposed to be the villain.

A villain who learns black magic and summons demons.

What do you think?

“I should enjoy being in a game world, right?”

No black magic, no demons to tempt me.
And the fate I have to live as a villain.
Everything is at my disposal.

I have one goal.
To get my own ending!
