The only canon romance in this series so far is between Guren and Mahiru.

The relationship between Yu and Mika is vague enough for fans to interpret as they please. Beware the fujoshi if you dislike BL because they will attack you with it.

At any rate, vampires have no sexual desires (or any other desires except for blood as time goes on), so Mika really is not into that sort of thing. Mika's dying thoughts were the need to protect his family, and that is all he is doing. He usually craves a girl's blood rather than a boy's in the manga, but he has not tasted enough blood to develop much of a preference yet and may only feel that way because of Krul.

Unfortunately, Yu has shown zero interest in girls thus far, but he has been focused on killing vampires and is already losing all of his own humanity. Not to mention, there are only two girls to choose from at this point, and they are a terrible trolling duo. I see Yu as having a crush on Mika, but, like I said, anyone is free to interpret it as they want. I see people not in romantic relationships flirt much more than that on a daily basis.

(Actually, there are more people, but they would be slaughtered the moment a battle breaks out.  Becoming a monster is not really a good way to get a date either.)

I personally do not care whether the characters end up in heterosexual or homosexual relationships or even no romatic relationships at all. I do like Krul and Mika quite a bit.
