Stella Nocté

Everyone has a gem in their heart, showing their hopes, dreams, and wishes.
But, when a gem is corrupted, that holder becomes a monster of the devil.
But these monsters hide in the shadows, catching, killing, and eating their victim's gem.
The devil has 7 main monsters, generals per say, of the 7 worst sins.
But, a secret school was formed to fight these monsters and battle the devil, and so this is where our story begins, with
Charity being sucked into this war.
