[WSA 2024 Entry]

Matt saved humanity, but humanity betrayed him and murdered him and his wife, which led him to reincarnate in a Vampire World.

He quickly realized that he had been reincarnated in a unique body that, among vampires, would make him look like a genius. In addition, he has several powerful abilities that no other vampire has.

This time, he will cling to this new life to become as strong as possible to search for his wife in a world of magic and vampires.

In addition, he will try to walk the path to become a True Vampire, a Vampire Progenitor!

At the same time, his desire for revenge burns within him...

There was once a hero.

Unique black hair. Excellent eyes. Contrary to his delicate features, he who had abnormal strength was called the Otherworldy Hero.

At the hero’s long adventure (up to the point where his wooden sword that had been kindly granted to him by the king was replaced by the holy sword blessed by the holy maiden) he saved the prince that had been kidnapped by the demon king, and so the kingdom was swept by worry.

The hero’s strength that could fell the demon king was deemed too dangerous to leave unrestrained.

One advisor spoke up. Why not marry him to royalty?

The king thought that was a viable option. Family, to an alien from another world would be the best of chains. There was one problem. The king was abundantly blessed with sons and had princes galore, but not a single daughter.

Ho, and it wasn’t like I could marry off two boys.

At a burst of inspiration the king slapped his knee.

That was it!

You just had to turn a prince into a princess!

And so the hero ended up in a position to be marrying a man.

This story, is a tale of the aforementioned otherworldly hero, and his bride, the former-prince-now-princess and their ridiculously hilarious marriage.
