One common theme is the struggle between their different natures. Since Yuu is a demon and Mika is a vampire, there's often a conflict and a need to overcome their natural instincts to be together.
The theme of redemption can also be seen. For example, if they have done some bad things because of their demonic or vampiric nature, they might try to redeem themselves through their relationship. And sometimes, there's a theme of finding a place in the world where they can be together without being persecuted for what they are. This can lead to interesting plotlines where they search for a safe haven or try to change the world's perception of them.
The theme of sacrifice also appears often. Mika might be willing to sacrifice anything and anyone for Yuu's sake. This shows the depth of his yandere - like love. Additionally, there's the theme of internal conflict. Yuu may struggle with his feelings towards Mika, as he has to deal with Mika's over - the - top behavior while also having his own emotions for Mika.
