The Grand Traveler Never Gives Up!

After finally rescuing his sister, Lumine, whom the Abyss Mages had deceived, from the edge of the world (not really), Aether thought that was the end of it. He could leave Teyvat and go play in other worlds. But to his utter surprise, just as he opened a portal to another world, his hand slipped because of a wind slime, and he was separated from his sister once again. Lumine: Uh... Aether: Uh... The Anemo Archon, who had caused this little mishap, awkwardly stuck out his tongue. Ehehe. In short, Aether sets off to look for his sister once more, bringing along the companions he befriended on his journey to find her. Aether: Since you're the one who caused this, you're coming along to help me. The Anemo Archon, Barbatos (Venti): Uh... Wait, Zhongli's caused you trouble too! Bring him along! Aether: Fair point. The Geo Archon: What does Zhongli have to do with me, Morax? Aether: Liyue can manage without you. Why not come with me to see other worlds (and find my sister [crossed out]) and discover more interesting things? Zhongli: Heart pounding.jpg P.S. Venti's white stockings are amazing! So is Aether's exposed stomach! But this is a story about Aether x Xiao. The Geo Archon is a father figure [crossed out], an old friend from another generation, and Barbatos is a close friend. Lots of headcanons ahead. Be warned: After Lumine goes to another world, the shock makes her lose her memories, and certain unavoidable circumstances change her hair color. Her constitution hasn't changed, though, which leads to [beep, ] Manually avoiding spoilers. The secondary couple won't be revealed for now to avoid spoilers. They're connected to the Taoist priest next door. Theme: A family should all stick together
