What would you do if your planet ceased to exist after a nap?

Once upon a time, there was a princess…

Scrap that.

Once upon a time, there was a hermit called Yao Si.

She was an orphaned hikikomori who lived a peaceful and mundane life in her cosy little apartment.

Just when she thought she’d live out the rest of her mundane days… she died.

By a strange twist of fate, she was somehow turned into a vampire, even worse, a fifth-generation weakling with no combat ability at all.

Vampires had their own little secret society, cultural feuds, and called themselves bloodlings.

So, a miracle occurred…

When she was woken up from a millennnia-long nap, she found that her beautiful mother planet Earth had ceased to exist.

Even the oldest bloodling in the entire universe was now one of her grand [ times infinity] child.

Everyone will have to call her “ancestor” from this moment onwards!
