The well known but mysterious 1 trillion floor Tower of Valhalla appears across Earth, and reaches hundreds of other different worlds, in which people and other beings are always ready for; for the one who reaches the top of the tower and defeats the one at the top will gain immortality, wealth, and power. Each floor is cleared with a certain number of points, in which those points can also be used to level up. Sho, a 17 year old high school delinquent boy with a rebellious attitude, trust issues, and a reckless mouth, lives alone, without anyone, in a run down abandoned warehouse. Plus he has no money, and has to steal food in order to get through the week. He’s never felt like getting a real honest job, and has never worked hard for anything in his life. He just takes it. After getting into a heap of trouble, that’s when the mysterious Tower of Valhalla shows up. Yeah, Sho enters the Tower without hesitating, but once he goes in, everyone else starts off with powers and abilities to help them, Sho doesn’t. All he has is a butterknife. But as time goes on, and Sho gets stronger, he has a system different than everyone else’s, and his power becomes limitless..with the potential to become stronger than all beings in the Tower of Valhalla.
