A somewhat different isekai in which the protagonist has the power to “cheat”
I learned a cheat skill in another world and also became unmatched in the real world tells the story of a boy who, after a life of bullying, finds the door to an imaginary world parallel to the real world. This new reality makes things easier for him by receiving an ability that allows him to “cheat” and another that allows him to easily teleport from one world to another. Can the protagonist change his life?
