Vicente had no clue about the ancient demon and Hoaquin agreement! And the ancient demon is why Hoaquin had control of the main body!
you said that hoaquin has not idea
But in chapter S2CH182 hoaquin
Explained to Vicente and David
The demon agreement and how
He fooled them into a trap to be the center
From the start when WHITE lost
Vicente took control only because
Hoaquin ran away from the position
After the FB not because Baam absorbed
The demon, in fact the demon spell is what maintain
The union of the 5 siblings
In chapter S3CH97
White said that vicente also
Mastered the spell to use that
Demon and that’s why both of them
Are the only ones who can be the center.
