Yae from Genshin Impact is my sister

Summary "Little guy, you've been following me all this way. Do you really want to become my apprentice? You should know that I, Gongsi, am usually very busy.""But, I really want to become stronger, you big fox demon."Looking at the child with white fox ears and tail in front of her, Yae no Miko smiled slightly. "Senior Fox Palace, you can't escape my grasp now.""It's not impossible for me, Tsukasa, to teach you how to become stronger, but I don't want to be your master. The word 'master' makes me sound really old. From now on, you can call me Tsukasa-neechan.""It's not impossible for me to teach you my skills. As long as you can persuade, no, convince a shrine maiden to live in Narukami Shrine, I will teach you all my skills."
