WeltStelle

WeltStelle is the het ship between Welt Yang and Stelle from the Honkai fandom.

Canon
Welt comes from the planet Earth and has saved his world many times (even inheriting the name of the world in German - Welt). He is also a teacher and an animator. Stelle is most likely an artificial human, as the first time we encounter her is when Kafka stuffs a stellaron into her chest. The only goal she has is to reach the end of her journey. They both travel aboard the Astral Express, following the path of the Trailblaze and becoming the nameless.

Today is Yesterday's Tomorrow
Welt first appears in the Trailblaze mission "Today is Yesterday's Tomorrow". Stelle blocks a hit from the Doomsday Beast for March 7th, but the stellaron in her body ends up having an adverse reaction to the power of destruction. Just as Stelle is about to blow up the space station, Welt appears and knocks her out with his cane. This action subdues her. At March's questioning, he says, "They're okay now. Let's talk somewhere else."

Stelle can talk to Welt during the mission, where he thanks her for saving March 7th and worries about the stellaron in Stelle's body. Welt also gives Stelle some advice before the jump, saying that she should close her eyes, as that helps with dizziness.

Jarilo-VI
Himeko recommends the younger members of the express go to Jarilo-VI themselves, but notices Welt's disappointment, stating that he will be able to go on an adventure soon. Welt and Himeko silently watch Stelle, March 7th, and Dan Heng from the express. There are times where Himeko is unable to quell Welt's worry, but she manages to convince Welt to stay in the Parlor Car. After Stelle defeats Cocolia, Welt works to seal the stellaron before Stelle comes back. He expresses pride at Stelle's first mission and is willing to answer her questions.

Windswept Wanderlust
Welt is finally able to go on an adventure with the March and Stelle. They save Tingyun from a group of Mara-struck, and she brings them to Fu Xuan and Jing Yuan.

Quotes
"Y'know Stelle, you remind me of the main character in a cartoon or something — you seem to attract companions out of thin air... *sigh* I hope you don't mind me saying that. It's just... it seems like my own chances of going on an adventure have plummeted again..."

Fanon
WeltStelle is a rarepair in the fandom. This is mainly because Honkai: Star Rail is a relatively new game. Many fanfictions are written about their romantic relationship as well as their friendship. A common theme of all of them is Stelle worrying that she is not enough, as she believes all she is is the stellaron, and Welt comforts her. Rival ships to this one include LuoWelt and VoidWelt.
