I believe the seraph characteristics would overrun him if his demon side weren't there. Since he has completely released Asuramaru from the curses restricting his power, I doubt Asuramaru will be turning of his demonic influence any time soon. Becoming a vampire might have a similar effect to becoming a demon since vampires are related to demons. Turning Yu from a demon into a vampire, kinda like what happened with Mahiru in the Catastrophe LNs, might be effective for a little while. The seraph part of Mika might likewise be keeping his vampiric characteristics in check, which might explain why he is so odd for a vampire.
