Frankly, it makes sense. The MC addresses this himself in discussing his decision to attend the school in the first place. He felt compelled. You could* argue it's due to the bond between the souls healing, but why would it already have drawn in so many supernaturally inclined individuals, including his ex? The veil is thin and a fragment of Eden is present. Ok. From there, why would supernaturally inclined individuals not run their mouths about being supernatural beings? Well, that's a great way to end up dead.
I have a couple complaints. The first complaint is our hunter should be much more conflicted about Rayne. And I think Rayne's power is too understated - we're talking about one of the entities that inspired modern day vampires. The biggest thing that changes is the bodily fluid they feed off of.
You definitely could argue that it might necessitate a bigger event for them to reveal what they are to each other. It could work, but there needs to be more build up or blow back. It hits too fast and is immediately resolved. Keira reacting more negatively to Rayne would likely fix that.
I'm fine with the fact that it took a trigger for Rayne to actually activate her strength to allow her to go toe to toe with a vampire. Yet I really don't like how succubus are being treated. Lilith herself is often, historically, portrayed as the first succubus and the mother of both. I'm kinda forced to assume that you got the vamp connection to Lilith from watching Supernatural, where succubus never truly show up.
Then the issue of people being able to sense Lilith gets really murky and makes too little sense. Rayne SHOULD be able to sense her, if only due to the change in our MC's aura/power. Lets say our MC starts as a candle, Selene is the moon and Marie is the sun. She should notice the MC going from that of a candle to at least a flashlight, which would evoke as much of a response as coming home and realizing your SO suddenly shaved their head. It's kinda insignificant as far as changes go, but still plainly obvious and needs addressed.
Overall, this instantly jumped into my list of favorite VN's bc you do properly hit many emotional beats. The problems I had can generally be easy to overlook or simple enough to retroactively fix. I'd also suggest adding some more dark gothic aesthetics like what Ocean is showing he's doing with Veiled Whispers. So far, what you've shown is very Texas Chainsaw Massacre vs what he's doing being Bram Stoker. With so much supernatural influence, dark gothic might be a bit cliche, but it's more fitting. Even if only rarely.
Sorry for the encyclopedia length response, but if I genuinely didn't really like what you're doing here, it wouldn't be worth the effort of posting and giving feedback at all. I could sit here and say this or that sucks, you might hate criticism, but no one will ever be able to say my criticism isn't constructive. And might not like the criticism, but I really like your work, and I only want to see you get better bc your work is very good.
