I thought when maika told the same that ibuki was Type A and her mother+father were Type B blood so I thought that he's going to realise that Ibuki is adopted (and it's gonna be a plot twist )
There's not any chance for 'a person' to be type A when both his (biological)parents are type B. Parents (both with type B) can only produce offsprings of either type O or B
