The Inventor. Senku Ishigami X Reader

Shinsou (y/n) was, for lack of a better word, a weirdo. she was obsessed with robotics, tiny foods and all of her experiments. She had a hard time making many friends with her blunt attitude and long winded explanations. After getting into U.A though, she found someone just as weird as her. Mei Hatsume. It only took a single class period for the two genius girls to become fast friends, instantly getting to work on an invention all their own. It took them several months but finally, they were finished. it was a simple little ray gun that could be used to teleport anything by reversing it's cellular structure from one position and moving it to another. sadly, much like the two's other "babies" it imploded, taking poor (y/n) to another dimension much like her own but without Quirks. (y/n) was trapped in this unknown world for four years straight until a bright green light enveloped the earth, trapping all of the humans in stone. This is the story of (y/n) and her new favorite humans using science to further human knowledge by literal decades in just a few short years while also trying to come to terms with the fact she will never be able to go home.
