The story is good. I won't say it's SuperWriter's best work. Though SW has written some impressive pieces, they can't all be bangers. While the direction can be somewhat predictable at times, tropes being what they are, the story itself is a unique telling and is well told. However, I will caution the underpinning premises of the MC's origin take some liberties with the "science" bits that are injected into the plot.
For starters, not really sure how a vampire is supposed to be literally born when the circulatory system is pushing blood at such a slow rate as to make molasses seem fast (I think I recall something like 20 over 4?). Either the circulatory isn't strong enough to push the blood or there's simply not enough blood to support the additional life... unlife? On top of that, with such a low blood pressure, it would be highly unlikely our MC would have the blood flow to get Little MC up.
Anyway, I understand we're meant to suspend our disbelief, but it's far easier to do that when you aren't inserting science on us. People suspend their disbelief for magic and the unknown, not for everyday science. This part of the story feels contrived in a way to evoke feelings of Twilight but without all the unnecessary sparkle and tacking on a harem. Approve the harem, not so much the Twilight.
Lastly, a vampire spawn in a human mother would just drain the mother--that blood is dinner, and the kid'll eat well. Meanwhile birth from a vampire mother would kill the child (in this universe, vampire blood is poison to other vampires, unless we handwave that for the mother). Now of course, conceptually, it's "poison" to circulate the wrong blood type in people so it sort of makes sense, but it isn't explained like that in any roundabout way by the two medical students, leaving me to believe it's more like eating rat poison than getting the wrong blood type... and that's no good for a vampire kid.
Setting aside the general premise of our MC's existence, I'm also bothered by the vampire LIs confusion over common things. I get the part about not really understanding technology, they are in their 60s (but don't look a day over 21)... but they're only in their 60s. How do they not know what camping is? It's not a foreign concept for characters that would've come about around 1960. If you're going to do this, at least make them a little older. Like... maybe 300, 350, many generations older. I mean, there's a good chance they would still understand the concept as they've had to adapt to the changing times, but at least there's some wiggle room.
Outside of the question of how our MC exists (and silly character misunderstandings), the story is good. (slightly spoilery, nothing big) Some mythical BBEG comes back to haunt our cast on the 15th anniversary of the MC's vampire father and human mother passing, and only he, the daywalker, the man between two worlds, the... Sun Breed... only he can be the one to fix this as the child in the middle because of the tenuous threads holding a secret mixed humano-vampiric society together.
Of the LIs, my favorites are Camilla and Aditi. Camilla because of her personality, which is similar to Najah but without the violence; Aditi because she's hot and rational. Najah's a little too campy, it's difficult to take her seriously at her most violent when half the time she acts like a big kid playing Inquisitors and Vampires (it's like Cops and Robbers, but more fantasy).
Graphics are pretty solid. Animations are short and basic, but good. I watch an animation, I don't feel like an emphasis was put on a single part of the model for movement. No, everything moves and I really appreciate that level of detail.
Sound is good, no complaints there.
Going to knock a point off for the story feeling a little contrived and asking me to suspend a little too much of my disbelief while trying to dip the sci-fi pen into the fantasy ink well, but other than that it's a solid outing. Four stars.
