A man was about to commit suicide and decided to search for a way to die on the internet, but then he found an odd site that asked a lot of questions and had a point based system that allows you to create skills for a character. He took interest in it, and when he was done setting his character, he was asked, “You will now be transported to a world with the settings you chose. Coming back is not possible. Do you still accept?” Without thinking much of it, he pressed YES and found himself in another world with the skills he chose to have.

I originally thought this was a world like an ordinary urban novel…Drawing comics by myself, traveling is pretty good.
But tell me, what happened to this magician called “Emiya Kiritsugu” who jumped on my face?

“I’m a warrior from the alternate universe.”“The Goddess summoned me to this world to defeat the Devil that has imperiled the world and to restore peace to the world.”“I understand that it’s my cardinal duty. Since I’ve been summoned to become a Warrior, I’ll do my best to beat my opponent even if he’s the almighty Devil.”“Don’t ask me why. That’s what the book says.”“But… isn’t this development straying from the plot?!”This is the beginning of a scam in an alternate universe. It is also the story of a warrior with a mission to defeat the Devil. At the end, he realized that he had been duped instead.
