super hero no sekai de tachioujou shi te iru seimei no haha (broken au x bnha)

Earth is thrown into the BNHA universe after having been destroyed by the moon revolution, trapped inside a human body that of a 14 year old Earth is thrown into Japan where superpowers are the norm, unable to leave her planet surface like normal Earth lives on the streets before Eraserhead takes her in and with a lot of planning she forms a story that she tells to Tsukauchi and Eraserhead, detailing a life where she lived in the forest filled mountains in Japan faraway from modern society and that her village was attacked during an uprising and that she was badly injured and had to runaway due to her fellow villagers forcing her to run for her safety, after being chased by the enemy as she tried to get to safety she fell down a cliff and lost consciousness as she fell into a steep river which drifted her down the mountain and farther away when she was unconscious. she spun her tale and thankfully due to her not truly being human and a celestial body his quirk didn't work and as such everything she said was known to be "true" and such she was taken in by Eraserhead and she started her life to train being a hero.. after she made official registration documents it was easy passing off her celestial powers as quirks weakened as they are they were more powerful then an earthling fitting of her stature being the mother of all life even if this planet wasn't hers originally it was hers now after she was able to link her divine essence (somehow these terrestrial planetoids aren't even sentient they were just their as some husk it was much easier delving her consciousness inside the planet taking over her different planetoid)
