Entropy Invasion from the Start: Protecting the Best Kiana

Su Lin transmigrates into the Honkai world and becomes a specimen bearing Kallen's name in Otto's laboratory.

Thus begins her life living together with the Valkyries.

Kiana: Please, Sister Su Lin!

Su Lin: My adorable little sister! Don't you know your big sister is a failing student too?

Kiana: How can this be…? I'm going to fail again, and Mei's going to lecture me again. Waaaaah…

Su Lin: Teacher Himeko, how can I become as magnanimous as you?

Himeko: That's an inborn advantage, and it can't be changed. But if you really want advice, I do have a method that might help.

Sister Su Lin, will you stay by Kiana's side all the way?

Of course! My adorable little sister Kiana, I'll stay by your side all the way. Even Honkai won't be able to separate us.
