After a Shonen Manga Crossed Into Teyvat and Changed the Tragic Ending

We've seen the people of Teyvat help writers and the Demon Slayer Corps with all kinds of troubles. Now it's their turn to help the people of Teyvat! 1. Climbing the tower to challenge Decarabian's divine sacrifice The sacrifice raised their prosthetic arm and cut down the arrow that had ended the nameless boy's life; 2. The gravity user who tramples a god and rescues an innocent adeptus The mafia of Yokohama cuts the chains holding the adeptus captive, returning freedom and sweet dreams to the Golden-Winged King; 3. The smiling master, bearing a curse, welcomes a failure with nowhere to go You are neither flawed nor a failure. You are a real person, born with a future ahead of you; 4. Flames rise from his sword as the grinning big brother takes on the dragon's attack Whether you're a pawn or a descendant, the Ragnvindr family will always save a place for you. 5. Golden butterflies flit by as the grinning, cleaver-wielding medic rushes to Khaenri'ah to save people "Oh my, Zhen, you're hurt." 6. "I wished to buy osmanthus wine and share it, but sadly, my old friend..." "I'm right here." The pint-sized great detective comes over holding the Stove God by the hand. "Lulu~~" Behind them, someone says, "You guys are all inferior to me." "Guizhong!!" 7. The bandage-wrapped man, once again holding a girl's hands and begging her to die with him, gets kicked to the ground. "You may have awakened us siblings, but stay away from Lumine!!" "Oh? Then, Aether, would you die with me?" The girl raises her blade. "Pervert, stay away from my brother!!" tips: 1. Reverse transmigration. They transmigrate to Teyvat to deal with all the angst. No fixed protagonist. 2. Ensemble cast, no pairings. 3. No Sumeru. There may be a few original settings. Theme: To be determined
