Seven days before the contest, Carbuncle had finally made a contact with Felix and the rest from the egg.
The daily feeding of energy had paid off faster than anticipated since Carbuncle's consciousness was already developed instead of waking up as a newborn consciousness.
He had told them that all the gifts were now owned by him. In other words, if Felix carried on feeding him, he would be able to be reborn with all of his strengths.
However, Carbuncle wanted none of that and had them cut off the feeding since he preferred staying with them in the consciousness space.
Plus, he refused to be reborn unless their plan to revive his wife had succeeded.
If it wasn't for Felix being required to travel to Lady Sphinx's lab, so she could supervise the bestowal, Felix would have already gotten the manipulation by now.
Unfortunately, he couldn't travel there when there were merely seven days before the contest.
