Red must confront the truth: he has lost. How then can he get stronger? Jirachi is awoken from its sleep early by Red, and in its grouchy state sends him far away to an underground region sealed off from the rest of the world: the world of Undertale. The problem is that he has no idea how to get back, and half of the monsters down there are out to kill him. Can Red make it back alive, and will he get stronger as promised? Only one thing is for sure: he is in for a bad time.
