It turns out that my Yandere playmate online is my Homeroom Teacher - Chapter 5: Glow up!

In a fantasy world ruled by kings and queens possessing great magical power, Kant Icurus Maybale is the only prince on the Aceaton Continent who does not possess magic. However, what he does possess, that nobody else does, is his past memories of the time when he was a Mechanical Engineer on Earth. With nothing but knowledge, brains, and wisdom, he dares to bring this medieval-esque fantasy world into the industrial era, and gain unimaginable wealth and power. Along the way, powerful forces that feel threatened by his rise in dominance will do whatever it takes to bring him down! Will he be able to conquer the continent, and potentially the world, to usher in a new age, or will he get crushed by the existing world order?

A life filled with regrets.Once he realized his faults and decided to lead a new life, it was too late.His family was already gone.He had borne through each day with pure rage.Finally at the end of his misery, his wish reached the heavens—an unforgiven one.He goes against fate to raise his sword.

It all started with a Book review…[To Kill A Demon Lord…] had everything; It had Magic, It had action, it had an abundance of interesting characters and—probably most important of all—it had Vampires.Kevin (Username: Kevin_The_Man) enjoyed the read. Stayed up to date with every chapter update and it quickly became his favorite Webnovel… That was until the Author killed off his favorite character, Caius Von Helsing, A Vampire Spawn who spent most of the story frustratingly resisting his Vampirism so as not to ‘become a Monster’.Kevin quickly wrote a review expressing his dissatisfaction so naturally, when the Author replied and asked for Kevin’s help in making a revised edition of the story, he quickly accepted…… Only to fall asleep and wake up in the world of [To Kill A Demon Lord…] as none other than his favorite character, Caius Von Helsing, the Vampire Spawn.Kevin—now Caius—quickly discovers that there is so much more involved in making a ‘revised edition’ of a novel than simply writing it. And that there are powerful forces that especially want Caius to die and stay dead…… But that death is still quite in the future so Kevin—now Caius—is quickly optimistic.He has a mission now;To enjoy the wonders this world has to offer—as the original character never would—by fully accepting and evolving his nature as a Vampire.

[MATURE CONTENT WARNING: 18+ ONLY. Contains explicit smut, omegaverse, knotting, and mpreg.]“Fuck, still so tight.”That's the first thing I hear after dying.Not a heavenly choir, not a wise guide explaining the mechanics of reincarnation, just a voice like dark honey and broken glass, breath scorching hot against my neck, and a body that absolutely isn't mine rolling its hips back like it has no objections whatsoever to what's happening to it.I have objections, so many objections.My body has apparently decided to hold a separate meeting without me.I was twenty-eight, overworked to the point of literal death, and had never so much as kissed anyone seriously. None of that seems to matter to the omega body I've just woken up in.. currently making desperate, broken sounds into expensive silk sheets, trembling around a knot that shouldn't feel this good, this full, this.. right, while my actual mind is still standing in the corner going what the fuck, WHAT THE FUCK???By the time I finally see his face, it's far too late for dignity. Gray eyes cold as a winter storm, features sharp enough to cut, the kind of beautiful that doesn't ask permission before it ruins you.It gets so much worse when I learn his name.Wuchen Bael, my sister's fiance, the man who looked me dead in the eye afterward and said, without blinking..“Round two?”And I haven't even gotten to the part where I find out I'm pregnant.
