The Seven Deadly Sins

History
These are the Seven Deadly Sins that will appear in "Highschool DxD Almost a Hero". These were the Original Lucifer's strongest weapons against the fallen angels and angels faction.

After the Great War and with the death of the Original Satan Lucifer (who they consider father) with nothing left to do they just used their powers to destroy the Earth and Underworld not caring about anything else in the world but to fulfill their desired sins. So the current four Great Satans had them sealed up inside a ancient tomb so they couldn't harm anyone.
