I Own a Demon Castle

Leisen is summoned by a beautiful girl from another world, and a game called Castlevania comes along with him when he transmigrates.

He transforms into a Vampire Progenitor and becomes the lord of Castlevania.

Castlevania can create all kinds of dark creatures, from goblins to bone dragons, and of course, the alluring succubi everyone loves to see.

Darkness descends, and war engulfs another world.

The king pleads, "Please stop fighting. I'll marry my daughter to you, and you can take your pick of my three princesses."

The pope declares, "Changing my faith is impossible. It will never happen in this lifetime."

The saintess cries, "Don't come any closer!"

The gods shout in unison, "We can't afford to offend him!"

After wreaking havoc across the other world, Leisen unexpectedly discovers that a portal he built leads to Earth!
