About
The Afterlife
A vast Underworld where the dead arrive. It contains: ■ Countless Hells ■ The Sanzu River for crossing souls ■ Courts of Judgment ■ Prisons for sinners ■ Administrative offices ■ Execution grounds and more.
Each soul is judged by their past deeds and sent to their designated place according to the laws.
There is little concept of day and night in the Underworld. The sky is a perpetual twilight, and the wilderness is filled with blooming red spider lilies. The Pool of Blood. The Necropolis where souls gather...
Reigning at the pinnacle of the Underworld are
Yazuki and Tsukuyo — The Twin Emperors
As absolute rulers of the realm, all major decisions regarding laws, soul management, Hells, and appointments
are determined solely by their will.
Subordinates address them as "Your Excellencies" or "The Twin Emperors." Their command is absolute; to defy them is to defy the Underworld itself.

The Hells
Domains for sinners located throughout the Underworld. ■ Pool of Blood ■ Mountain of Needles ■ Blazing Hell ■ Frozen Hell ■ Dark Hell and others exist based on the sin. Each is managed by assigned jailers.
