Synopsis
It’s said that once you die you’ll meet an angel or a demon.
There are five main angels, and five main demons.
All the angels' names were lost to history.
However, the demon's names are vividly remembered by all - the names drilled into each and every child’s head, from birth to death.
Nightmare, Error, Killer, Horror, and Dust.
Greed and pride, wrath and ignorance, insanity and lust, gluttony and paranoia, sloth and neglect.
It’s also said that sometimes even the purest souls get lost in the afterlife, facing the demons, no matter how good they were while living.
That was probably why Cross was sitting in front of a very confused, goopy-looking, skeleton.
------
Or, more bluntly, a demon reverse-harem where the slow burn is so slow that you probably won't see it until chapter 40.
