Kirito and the Underworld

Kirito and Eugeo were both born in Ruild Village but hate the way the Integrity Knights maintain order. So both of them decided to do something about it. While they were doing their sacred duties as usual by chance Kirito encounters Alice Zuberg while gather materials. While at first a normal encounter, unknown to him this encounter will change not only his life but the life of Everyone in the Underworld forever.
