Male Kamen rider Ziva reader x Monster High

Kamen rider Ziva is a Fangire rider, Zivat is the Kivat that allows him to transform, main colors are electric blue, black, and silver. Also, different arms monsters, Akuma Crossbow(demon crossbow), Kitsune Rapier(ninetailed fox), and Mira Staff(mummy). I dont know Kiva's full story, so sorry if you have to fill blanks, this is after Kiva ends, I'd say 5 years. Their are four fangire royal familys, the reader is from one. I'm assuming that Kiva is from another and was married to the heiress of another.

The reader was told his mother died giving birth to him, but then this weird bat looking thing appears out of no were, saying his mother was a creature made of stained glass called a Fangire, and apparently a princess at that. His mother actually died from being hunted down for treason of marrying a human, but no one was aware that she had a child and that she ran and left her child with her lover, sacrificing herself. But the reader didnt believe it, as it was to far fetched. The reader was going to his first day at monster high, but the bat thing wont stop following him, he had to shove it into his bag when some other student, monster one, arrived at the bus stop. Later a stray Fangire, a member of the readers mothers disbanded court, arrives searching to eliminate Zivat, but not without deciding to attempt to snack on some student, to which he didnt succeed. Soon Zivat tells the reader of the power he can use with Zivats help, and seeing as he was actually liking Monster High, and that Zivat had somewhat grown on him, he decided to try. Then infront of everyone, he Henshins for the first time into Kamen Rider Ziva. The stray fangire realizes that the reader is the child of his previous Queen, who he had seen as damned for breaking the Fangires rule, at least two Royal familys rule, as two of them had removed that rule.
