All the seven weapons of Jin returned back to his body.
He didn't like using his [Ex-Burst]. In fact, he despised it.
For someone like him who was incarnate of the darkness in the world using the power of light such as hope was disgusting.
However, that was the only thing he can do given the circumstances.
Jin's ability was based on an artefact you might have heard of before. The legendary [Pandora's Box] from the myths of Greece.
It was a box given to an innocent girl for an experiment by the cruel gods. Inside it was the seven deadly sins that plagued humanity. In order to keep them sealed the only thing Pandora had to do was simple. She just needed to not open the box.
However, gods didn't tell her what exactly was inside of it. They just told her if she ever opened this box unimaginable bad things would happen.
The result was that Pandora opened the box due to her curiosity and released the seven deadly sins to the world.
