My girl is a...vampire samurai?! (MxF looking for female)

[HairyBushLover]

The plot would be about My character, lets call him David Evans, for a X reason (in which you and me will have to work on) meets a extremely hot girl and they accidentaly kiss. For David it was just an accident "great I kissed a hot girl like that" but for her...the first kiss means...marriage. This girl turns out to be a vampire...a really prideful one, but this girl is no normal vampire, she is a vampire samurai (to make her even more prideful) whose mission is to eliminate any supernatural creatures that threat against humanity. Now that she was "forced" to marry David she has no other choice but to live in his housee.

That is just the basic idea. We can discuss about the rest
