Davis felt that he needed a force to reckon with when it was time for him to finally leave this place since he guessed that there would be numerous blockades no different than life and death threats barring his path, but who were the people he was dealing with here?
They were Peak-Level Immortal Emperor Magical Beasts with prowess near the Empyrean Stage and had countless crimes posted on their heads and made to be prisoners here, so for him to recruit them without restrictions already placed on them would be no different than suicide.
Even if not for their crimes, it was unknown if they had a sincere nature other than the rabbit, so they could take advantage of him anytime if the situation calls for it.
Even the Variant Dark Dragon was smart enough to take advantage of the confusion his Calypsea had, although she was smart enough to see through it despite only being recently born, but who was to say that they wouldn't look for a chance to take advantage again?
