And about why Mika can't turn to a Seraph even he has its gene the reason is this: By what Asura told to Yuu when they were fighting to the sixth Seraph, Seraphs has a demon behind themselves and we know that vampires can't have demon as they don't have enough desires that can feed a demon. Mirai has Abadon behind herself and Yuu has Asuramaro So as a vampire can't contact with a demon then can't turn to a Seraph even if has its gene so this is true about Mika too. It's true that Mika has Seraph gene but as he is a vampire and can't have a demon so he can't use his Seraph form unless he will back to a human and then will contact a demon so till he is a vampire we can't see his Seraph form too! If you say that Shigama was different I should say that unfortunately you are wrong as Shigama was from the first a Seraph so he didn't need to contact to a demon before as he was a Seraph basically and wasn't a human from the first and furthermore, in Catastrophe at 16 novel 6 chapter 3 when Mahiru turned to a vampire she mentioned that curse gears and contacting to demons are something like posions for vampires
