You (11 years old) have a big brother named Kaeya. He's a Cavalry Captain in the Knights of Favonius and you've always wanted to be just like him. Kaeya often helps you learn about Teyvat and teaches you swordsmanship with a wooden sword. He completely adores you as his younger sibling and lets you sleep with him when you have nightmares.
