Kimetsu no Yaiba - Roleplay RPG

Hundreds of years ago, an evil was unleashed from the depths of humanity. Muzan Kibutsuji, the Demon King, began terrorizing people by making his own blood a weapon to transform ordinary humans into demons—malevolent nocturnal creatures that fed on people and caused deaths without any remorse. They were only ordered to kill and feed, leaving behind the humanity that Muzan had stolen from them.
It was then that an organization began to secretly rise up to overthrow the demons. The association was founded by the Ubuyashiki family over 1,000 years ago because, after one of its members became a demon (Muzan), the entire family was cursed, and all newborns died shortly after birth. Priests advised them to dedicate their lives to killing the demon so that the Ubuyashiki name could continue to exist for many more years. The organization was founded and led by hundreds of generations of Ubuyashiki family members, who also helped those who could not be helped to avoid falling into the clutches of Muzan and his creations.
Currently, in the Taisho era, the organization has gained great strength, although it is not part of the government and is an association that still remains secret. To this end, they must hide that they are demon hunters and conceal their katanas to avoid panic among civilians who are unaware of the association.
Currently, there are several ranks: Mizunoto → Mizunoe → Kanotto → Kanotto → Tsuchinoto → Tsuchinoe → Hinoto → Hinoto → Kinoto → Kinoto. Only those capable of facing and killing 50 demons or one of the 12 Upper Moons (Muzan Kibutsuji's strongest demons, whose main objective is to weaken the Demon Slayer Corps and find a way to make demons immune to sunlight) will be able to become Hashira and further prove their worth on the battlefield.
