In the Year 393 of the Jin Calendar, the Sixth Demon King massacred the city-state of Yasi.
In the Year 413 of the Mu Calendar, the Sixth Hero fought the Sixth Demon King to the death in the city-state of Peter. Both died, the Hero paying with his life to kill the Demon King, and they were reincarnated.
In the Year 425 of the Mu Calendar, the Seventh Demon King and the Seventh Hero meet.
The cycle of fate descends upon this island once more. The misfortune of a past life falls upon a young man's shoulders, and the companions who once stood side by side now turn their blades on each other.
If you insist on facing this world and declaring yourself its enemy, then I will turn my back on you and betray the whole world.
P.S. The blurb sounds very serious, but the author says the actual story is just silly.
