Definitely, especially the big focus on family the series cannot overlook actual blood related family members.

With Yu found and the rest of the squad aside from Shinoa on a path to escape, Mitsuba should be appearing more and good timing too with the Imperial Demon Army possibly about to fall with Shibuya, Mitsuba and Aoi have some hard decisions to make :O
