Deadly Sins (On Hold)

26 years ago a magical ritual has gone wrong and opened up hell, and combined the two worlds hell and earth.
People of Tokyo were in a battle they couldn't win, demons couldn't be seen by normal human eyes, so it left areas of the world in the most pain. There was nothing to do against a enemy not seen.

Now a group of new members join Seventh Sanctum a group of Demon Hunters with abilities and skills that excel over normal humans. Though when a certain recruit is brought to the organization, they see he hones most interesting abilities. And isn't as normal as he seems after one mission that turns for the worst.
A valued student is turned into the most wanted. And are the world's protectors perfect Saints, humanities protectors as they say they are, or another person who thinks there god?
