Jin Ishiwatari is just your normal, average high school student. But when a possessed vending machine claims to be none other than Satan himself and tasks Jin with creating the ultimate robot to conquer the planet, things get more than a little heated up.
Now Jin's life has gone to hell, quite literally, as he finds himself surrounded by a harem of demons and succubi who aren't exactly the best at their jobs. He'd sell his soul to be back to his old lifestyle in a heartbeat, except it looks like he doesn't have one to offer anymore.
An infernal, surreal comedy that is sure to entertain!
