Here is part 3 of the Vampire x Hunter Himi Au
Sibi has a maid, since he and his brother are... well lets say they are basically the adoptive sons of leader of this mighty Vampire clan (who will never have children of his own, because he is gay and madly in love with the leader of another vampire-clan who is half his ally, half his archenemy... it is complicated. Anyhow...) and that is why Siberu has his own maid, whichs name is Rui.
In any case, after Firey fell unconscious and Siberu failed in killing her, he had no choice but to bring her to his mansion. The leader of his clan, Ri-Il, is not suppose to know about any of this and so Rui has to help Siberu - although she is not exactly happy about it.
Rui is actually in love with Siberu and her instincts tell her immediately that this hunter woman did not just survive because she is the best friend of the hunter-princess, but because Sibi has feelings for Firey and Rui doesn’t like that at all. She wants her master all to herself. But usually she does what he tells her, so this time, she is going to hide the huntress for the time beeing.
Ri-Il is really mighty, so he will notice sooner or later that that girl is in his mansion, so Siberu has to come up with a plan really fast... but he is not exactly good with planning...
