[miHoYo Crossover] Just How Many Wonderful Little Sisters Does This Useless Brother Have?

Determined to help his little sisters become stronger, Aether charged into Teyvat. I'll pull for the strongest teammates, deal the biggest damage, and carry all the little sisters from different worlds! Aether clenched his fist. An hour later, Aether and Xingqiu and Barbara stared at each other. No problem! It's only a team with nothing but healers and sub-DPS (sub-healers)! I, Aether, will become the most dependable healer big brother to all the little sisters from different worlds! Xingqiu, behind Aether, hesitated before speaking. "Traveler, don't you think your plans changed a little too quickly?" A week later, Aether said with absolute conviction to Xingqiu, who had worked so hard to raise his entire team: "Xingqiu! Come on! Let's go fight the Oceanid!" Xingqiu seemed to see right through him. "Are you really going to use a Hydro character like me to fight the Oceanid?" Aether smiled faintly, revealing behind him his little sister from another world, standing with Master Diluc beside the Oceanid's pool. ○ This is the delusional novel version of the author's Genshin Impact gaming journey. Thanks to the little sisters who carried me in the early days of my game. Though I'm still not a reliable healer big brother, that's okay, because you are. I've settled in and am ready to be carried. ○ The protagonist is Aether! There will be some memes in the story! No CP, everyone dotes on him (I raised all the characters I pulled, so don't I get to dream a little?). Everyone is a sneaky little chicken! Aether is utterly devoted to Fu Hua! ○ The frequency of each character's appearances depends on how often the author uses them in their own game account. ○ There will be some Honkai Impact 3rd elements. The author is a Fu Hua fan, so you know what that means, mm-hmm. There may also be Nagazora City (?). Theme: As long as your companions are by your side, your wounds won't hurt
