In Black Heaven, you’re a former scholar and one of the last survivors of a plague that’s destroyed the world you used to know.

After nearly succumbing to the disease, your life is saved by a mysterious necromancer named No-Eyes, who offers you the chance to escape death forever and relive your past. All he asks are the souls of your former classmates:

- Ru, your shy but brilliant tutor
- Lyse, the fiery, sharp-witted debutante
- Izagi, the idealistic and stoic martial artist

As you return to the ruined academy where you spent your happiest days, you’re haunted by the pleasant memories of your old friends, and the line between memory and madness becomes dangerously blurred.
