I'm looking for stuff like Solo Leveling or Skill Board Adventurer! where magic appeared in the modern world and the world had to adapt to it. Preferably more action-based with monsters and people suddenly getting magic powers. In a way, I guess stuff like The Gamer or Monster ga Afureru Sekai ni Natta node, Suki ni Ikitai to Omoimasufit. Mainly Magic coming to this world instead of people of this world exploring magic worlds, but those are okay too. Thank Everyone!
