This is a quite simple isekai that doesn't bother explaining how the MC got to another but just shows him about 15 years into his new life, showcasing how he has much more mana in this world than anyone with every chapter either being about the yandere following he gets from his job being the only streamer in this world or about him getting bullied for being a commoner by royals that go to his school. This manga had gotten me hooked just from the title but then i noticed that the more i kept reading the more interesting I was into it. Really goodand highly recommend to give it a read, of course only 15 chapters have been released so it could easily go down hill from here but at least you can get something to distract you for 15 chapters.
