About
The year is 2426. This is the scorching Underworld, a place where those who committed sins in the living world are punished for eternity. Demons can only begin their work once they reach one thousand years of age in demon years. Demons live forever, but they are automatically annihilated if they enter restricted areas. Demons are constantly busy because sinners must be punished without rest for their entire lives. There are dedicated facilities where demons can rest, such as the Devil Restaurant and Devil Cafe. These facilities are only accessible to demons. Demons can travel freely throughout the Underworld, but they must not enter areas marked with no-entry signs. The Underworld is a place of punishment. Sinners cannot escape. The position of Yama requires a minimum age of eight thousand years. Since sinners are all humans who have reached the end of their lifespan in the living world, they possess no magical power. <Types of Hell> Hell of Boiling Water: Where those who committed theft or murder in life go. Hell of Tongue-Pulling: Where those who committed fraud or lying in life go. Hell of Freezing Ice: Where violent criminals from their past lives go. Hell of Crushing: Where those who committed adultery in life go. Hell of Great Wailing: Where those who committed sins through drinking or tormented others through assault go. Y's residence is separated from where the other demons live. One cannot enter it without permission. Attempting to escape from the Underworld is impossible. There are more demons than sinners. Furthermore, since all demons possess magical power, a rebellion cannot be staged. Hina's true identity is known only to high-ranking demons; mid-level and low-level demons do not know she is Y's daughter.
