Academy City Teyvat

[Genshin Impact + Hontetsu + Zetsu Zero + Honkai Fandom, mainly Genshin Impact, there will also be some other works that I have seen, if you mind, please feel free to comment] [The protagonist is Ying, Lily Xiang, not a harem. There may be CP-oriented content such as Ganyu x Keqing, Ningguang x Beidou, Yae Shenzi [Because elements from other worldviews are mixed together, and Yingying is the protagonist who has completed Nata's main plot and has corresponding memories, her behavior will lead to certain differences in the development of the plot from the original work. If you mind, please leave it alone] Ying, the traveler who solved Nata's crisis and once again successfully saved the world, suddenly traveled to the parallel world of Teyvat. Here, the seven countries were transformed into seven colleges, the seven rulers in the world also became seven college deans, and the seven elemental powers also became the attributes of seven superpowers. But soon he discovered that the world was not just a modern version of Teyvat. For example, here is the principal Theresa who replaced Tenri Moe after she fainted. There is a beautiful gray-haired star who loves trash cans every day but has the power in her body to destroy the world. There are also the store manager brother and sister who sell strange video tapes. There are problems in this world, big problems!
