The process should've been normal.
When merging a core directly into himself, the soul would normally immediately fuse within the core inside his soul realm.
That was how it had always been with his other creatures.
The soul would be assimilated before undergoing a massive change that would alter it into a core that represented the best of both, with the originator cores acting as the foundation.
Noah didn't expect this case to follow that same process.
And as he suspected, the moment the soul was brought into his core, its behavior had already begun to differ.
It fused with his core, his soul, but its consciousness didn't immediately disappear, remaining intact as it integrated like a parasite.
It wasn't rejecting him. Instead, it was attempting something far more deliberate, something similar to what Ailetta had done, but in a far less impactful way.
