How are the Honkai games connected?
HoYoVerse has made 4 Honkai games. (In order: FlyMe2TheMoon, Zombiegal Kawaii, Guns GirlZ, Honkai Impact 3rd, and Honkai: Star Rail.) They are all connected in a way.
These games aren't directly connected, so you don't need to play all of them to understand the lore. Simply put, every game is a bubble universe from the Imaginary Tree. That's why some of the characters appear in multiple games.
Important connections between Honkai Impact 3rd and Honkai: Star Rail are:
- Welt Yang is the same person in both of these games. He has arrived to the Astral Express using the 2nd Divine Key, aka the Cosmic Juggernaut. It's primary function is to observe and travel through bubble universes.
