As the battle between the human army and the Demon King's army intensifies, the first site the engineers arrive at is the extremely shady weapons factory in the Demon King's castle! In order to save the oppressed goblins, Japanese corporate warriors will start a revolution!! The closest thing to a god in this world is... an engineer!

The protagonist, Shibai, is knocked out by someone during a big job. When he wakes up, he's inside a large duct, where falling means certain death. An eight-person death game begins! The puzzles are supposedly solvable by a skilled engineer, but Shibai is actually just a con artist pretending to be an engineer. Can he find a way to escape? What will he do? What will happen next?
