Kent had already been made aware that the day his fate was complete, the heart demon that had plagued him his entire life would finally be purged.
That heart demon had been Dia all along.
She first revealed herself during the Primordial Era, and she had followed him throughout his 13 lives. So he knew that with Safira back, it was only a matter of time before things happened.
What he never expected, however, was the sudden awakening that took form in Dia the moment the Bond Meter struck 100% and his fate was restored.
The moment Kent's fate was restored, the power that had been planted inside her, turning her into a heart demon for Kent, awakened, and she had to fight to defeat it or be defeated by it.
Dia may have already suspected something like this would happen, so she had been preparing diligently, waiting for the insidious power that took her free will from her, turning her into a weapon that nearly claimed the life of the saviour of the universe.
