Welcome Aliens from wherever you are, sit back and relax as you will witness a new version of MHA with some plots of the canon can still be found, if you're laying in bed then continue laying down, if you're eating, focus on your food!.
The reason why I made it different from the canon is that I didn't watch the 2nd or 3rd and the following season of MHA, and here I was inspired by other Authors here in webnovel writing fanfic about MHA.
In addition, S1 scenes are there but not all of them still I can't promise to the following season's yet I will try to include and do some research.
