Ainsworth had realized that since his friends and acquaintances' backgrounds were improved while only his was nerfed, it was within his interest to make use of their background to supplement his own.
It was no exaggeration to say that both Rian and Dante were his sworn brothers so as long as it wasn't too big of a favor that their family elders would disagree to it, Ainsworth could make use of their background as if it was his own.
So, to compensate Rian and Dante and to further strengthen his bond with them, Ainsworth didn't mind carrying them in Otherworld Missions as the stronger they became, the more it would benefit him.
'Normally, an otherworld team could only have one to five awakeners in their team as more than that would drastically increase the difficulty of the Otherworld Mission.'
