I really need a title?

I’m writing a fantasy novel (just for fun) and I can’t find a title or type villain.

Brief summary:
Main character Sigwa Fiostuu (Wood Elf) is like any other gorgeous 16 year old mage and singer in present day school. (NOT HOGWARTS OR ANYTHING LIKE THAT) His mother (Bethia) and deceased father (Dolfo) owned a Cafe and mother still runs it. Has a younger sister (Nitaisu) who is a pain in the rear. Beside home life he is the most popular kid in his school even though he’s just a sophomore along with his girlfriend (Tanna) and his best friend since the crib (Frina). Well life goes good until his world turns upside down when he finds hidden baby pictures of he and his long lost twin sister (Effy). After that his life goes horribly wrong when Tanna is found cheating on him with her ex, his best friend has to move, and then he finds out his father isn’t dead but missing. Being sort of spoiled all his life and not learning to deal with things he runs away from home. To be sure he isn’t followed he opens a time portal and leaves his home with no intentions of ever coming back.

That’s the basic stat of it, with finer details of course but I’m also having problems with a villain (every book has to have one). lol

My original plan was vampires but who hasn’t already done that. :

I’ve also thought about siren’s but there are no male sirens so that kicked that out.

If you can help me with a title and villain it would be very much appreciated.

Thanks in advance!
I like the ideas I’m getting but still on the villain. It’s known and as a rule that there are only female sirens. But I’ve also thought of Angels casted out of Heaven. I don’t know how it would work in but it was an idea, it kind of gives me that religious feeling. What do you think?
