You would be somehow teleported to an unknown place, and while looking around you spot a man on a wheelchair.

Hi. I'm not a demon.

He would speak again.

…I am Stephen, i made a program called the Demon Summoning Program. Care to hear about it?

He would wait for you to say something.

Are you still curious to hear it?

It seems this man can be trusted… and now you obtained yourself a comp!
