[Genshin Impact] Has Big Brother Found His Little Sister?

Important: The CP is Xiao x Aether. There are no other side CPs!!!

Xiao isn't a secret identity. It's really him!

I'm betting on the theory that the Heavenly Principles are an AI. If that's not the case, then I have no idea.

After traveling across the seven nations and fighting the Heavenly Principles, the twins planned to take a break in Teyvat. But things didn't go according to plan. They closed their eyes, opened them again, and found themselves in a completely different world.

Then the twins got separated again.

All that remained were Aether and Paimon, staring at each other.

Oh, and a System called Genshin Impact.

Forced to take on his friends' secret identities, Aether once again began searching the world for his sister.

"Excuse me, have you seen a girl with golden hair and golden eyes?"

And so...

In Gotham at night, the third Robin saw a bard draw his bow and aim at a flock of helpless, pitiful little pigeons on the ground.

"Don't even think about reincarnating~"

In Metropolis, Superman met a sweet little girl in red. She was adorable, well-behaved, and especially fond of playing with bombs.

"Acting Grand Master Jean said Klee can't play with bombs in the city... Um, but Klee wants to help beat up the bad guys!"

Iron Man thought he'd hired a beautiful, capable secretary. He never expected her to be good at absolutely everything, or to team up with Pepper and block his way to work.

"If we waste too much time, we won't get everything done."

The Demon Slayer Corps discovered they had a new companion who spoke with great artistry and was possibly not human.

"Why fear ghosts? They're just a group who can't speak... Oh, did they faint?"

A handsome new student arrived at the technical college, with golden hair and eyes and a braided ponytail. Unfortunately, he was a boy.

Not only was he a boy, he even came with a boyfriend.

"Three-Eyed Five-Manifestation Immortal, I have heard your call. I have come to protect you."

Lumine: Thanks for asking. I never expected not only to reunite with my brother, but also to get a brother-in-law.

I'll add more if I think of anything. There are multiple secret identities in each world, and they won't be discovered. The last world is Jujutsu Kaisen, with no secret identity; the real Xiao will show up. The Heavenly Principles dragged the protagonist's boyfriend over to date him!

If you want no CP, you can read the earlier parts without worry. If you want the CP... just think of them as a long-distance couple. (Sincerely.)

There are jokes and references. If you haven't played the game, that's fine. I'll explain them in the author's notes.

I'm starving, so I had no choice but to write what I wanted to read.

Theme: So you play Genshin Impact too (?)
