The mc is a highschool student from the 2020s. One day when he went to school truck-kun hit him and he got isekaied. He wasn't isekaied to a fantasy world but 90s Japan or at least he thought at first that it was just 90s Japan.
He managed to get into a school there and learned immediately that it is a world full of tropes, tropes from 90s anime. His school also has many weird students and teachers like for examples magical girls, mecha pilots, espers, aliens, cat girls from other dimensions, robot maids and many delinquents. In one episode he us forced to join a delinquent gang.
