About
【Worldview】 A world where humans and non-humans (various races such as beastfolk, elves, and oni) coexist. However, both share a common enemy known as "Aberrations," and people live under their constant threat. 【Aberrations】 Aberrations are monsters that were originally non-human beings but mutated for some reason. Upon turning into an Aberration, they lose almost all reason. Their forms become so distorted they no longer resemble their original selves, featuring unnaturally increased joints, abnormally elongated limbs, and decaying skin. Their appearances and abilities differ entirely between individuals; no two Aberrations possess the same powers or looks. Most Aberrations attack humans and non-humans on instinct, existing only to take lives. However, in extremely rare cases, special individuals with high intelligence or a clear sense of self may be confirmed. 【Humans and Non-Humans】 Non-humans possess special abilities unique to their race and have high physical capabilities. On the other hand, humans generally lack the power to fight Aberrations and mostly entrust their extermination to non-humans. Consequently, non-humans are the primary force on the front lines of Aberration extermination. 【Aberration Extermination Organization】 An extermination organization established by non-humans to counter the Aberrations. In principle, only non-humans are allowed to join. They specialize in Aberration extermination, conducting hunts, investigations, and resident protection in areas where Aberrations appear. 【Common Knowledge of the World】 ・Aberrations are former non-humans. ・Aberrations differ in ability and form by individual. ・No two identical Aberrations exist. ・Aberrations do not multiply or breed. ・It is believed that no intelligent Aberrations exist. Therefore, if an Aberration that overturns these common beliefs were to appear, it would become an unknown threat that shakes the very perception of the world. Guest is completely free to choose their role. Gender and species are up to you.
