Genshin Impact: The Eighth God of Teyvat Is a Vampire Empress

Shenyu is a lucky Genshin Impact player (though not for much longer). Besides that, he's loved vampire princesses since he was a child. He has bought every volume of a certain Pineapple Bun author's vampire princess novels. He really wants to become a vampire princess just like the characters in those stories.

But...

A vampire princess claiming to be Shenyu's older sister barges into his home.

"Sis, tell me first. This isn't real, is it?"

"Come on, come on, it... really is. Now hold still while I awaken your bloodline."

"Help..."

After reincarnating, Shenyu thought it had all been a dream. But...

"Oh, my dear sister. Have you really grown so distant after just five hundred years apart?"

"Help... This is actually kind of great!"
