demon slayer upper moon 4

Dante saved the world from collapse and he is rewarded by getting killed. Within the hundred year reign of the strongest demon lord, most of humanity is wiped out. Ten valiant knights fought in the eleventh hour of humanity to vanquish the demon lord once and for all. Yet it is the eleventh knight that actually defeated the demon lord. A knight whose name is wiped from history because of the ten knights that betrayed him. Carrying curse and resentment to his grave, the hero resurrects to extract his revenge in the body of the new demon lord.
