Traveling Across Teyvat with Himeko

A quick note: The Himeko here is Himeko from Honkai Impact 3rd, not Honkai: Star Rail. If you haven't played Honkai Impact 3rd, go play it! The story is super sweet. You can skip the Honkai Impact 3rd chapters at the beginning and jump straight to the Teyvat arc.

Now for the main story: The male lead, Mu Xiao, has no System in the Honkai world, but he is half a Herrscher. (The author is laying some groundwork here. Anyway, the male lead's existence in the Honkai world is a bit awkward.) He transmigrates to Teyvat after Kiana becomes the Herrscher of Finality.

In the Honkai world, the male lead tells Himeko that he doesn't belong there, and she agrees to transmigrate with him to the continent of Teyvat.

[Hello, you two. I'm your System.] The System finds them midway through their transmigration.

[Outlanders, have you come to destroy this world or save it?] One of the Four Sustainers of Heavenly Principles.

[I never thought you'd make my wish come true. Ehehe~] The Anemo Archon of Mondstadt, Barbatos.

[It's been a long time, old friend. And thank you, young friend.] A certain old gentleman who enjoys tea and opera.

[This time, even if it costs me my life, I have to hold on to those hands.] A certain shut-in goddess.

“So you're just a wish-collecting device,” Mu Xiao said, looking at the System spirit.

[Ehehe~ That's right.]
