That Time I Got Reincarnated As An Abyssal Phoenix

In the world of that time I got reincarnated as a slime there are seven sins.

Prideful king Lucifer.
Greedy king Mammon.
Envious king leviathan.
Wrathful king Satanael.
Slothful king Belphegor.
Gluttonous king Beelzebuth.
Lustful king Asmodeus.

But what if there was one more sin, a sin that everyone who knew about it thought it was almost impossible to obtain. Follow our young mc as she tries to find her place in the world, while trying to get over her horrific past. This is the story of the sin of Sorrow.
