The S-Class and a few others watch One Punch Man. This on Fanfiction.net too.

This is basically the Teyvat people are reacting to different stories and eventsnwith the main focus of different version of Aether and his quests. (First two acts will be story quest of Zhongli and Venti. after will different version of Aether with different pairings) (Aether harem)

Ei doesn't really know what she's feeling, luckily Aether is there to help. My take on Ei's story quest.
