나 혼자만 레벨업 | L28, either the webnovel or the webtoon, both are nice. Takes place on Earth, but with portals leading to dungeons full of monsters.
싸움독학 시리즈 | L26, a webtoon. No magic, just regular Earth, but very action packed, and you see the MC progressively learning how to fight and getting stronger. Highschool setting.
외모지상주의 시리즈 | L27, a webtoon. Same studio as the previous one, still regular Earth, but with some strange things going on with the MC having two bodies. Again lots of fighting, but also a commentary on how appearance can change the way people are treated. Highschool setting.
튜토리얼이 너무 어렵다, both a webnovel and a webtoon. Somehow I can’t find it on Natively, but anyway, it’s still one of my favorites. Technically on Earth, but really it’s inside the tutorial. Features magic naturally, and lots of fighting!
신의 탑 시리즈 | L30, a webtoon. Full fantasy world, magic, and again, very much action packed.
약한 영웅 1 | L26, a webtoon. Regular Earth, lots of action, and the MC has a very… interesting fighting style, you’ll see. There’s also a kdrama based on it that’s quite nice. Highschool setting
