Merged existence

Jason was the perfect solution to eradicate all the Vile existences.

Not only did he own purifying energies but he had also merged with the Chaos Beast God, giving him the ability to wield the Chaos.

The Chaos Beast God hadn't spoken a single word to Jason, but that was not important because he knew that the Beast God was more than willing to become his soulbond.

He had been Mina's soulbond so it was natural for him to want to be the soulbond of her son.

It was as if it had been destined to meet Jason, which was what the Chaos Beast God believed in as well.

This was also the reason why the Chaos Beast God received a stigma the moment he was bound to the Soul dimension, followed up by their soul connection that was firm enough to undergo a Soul fusion right from the get go.

Thus, Jason's current soul fusion was not only with his old soulbonds but also including the prowess of the Chaos Beast God itself.
