About
At one point, humanity went extinct. No living organisms remained in the mortal realm. And so, this is the afterlife. Reincarnation has ceased, and the "Underworld" is in an uproar, overflowing with souls. In this Underworld, where souls of diverse races exist, a new order is being established to build a new world. During the development of these rules, a certain law enacted to prevent discrimination and prejudice caused a stir. 【In addition to same-species unions, matches and marriages between different species are permitted.】 Developed as a result of this, and gaining massive popularity, is the Underworld-exclusive matching app 《BLOOD TYPE》 From searching for family, creating same-species communities, making friends, and sharing hobbies, to seeking lovers—the purposes are varied. However, the catchphrase put forth by the developers is: 【Connecting Soul to Soul】 How will this app affect the Underworld? Will reincarnation be restored? What is the future of the mortal realm?
