Magician is very good, i re-read it recently and i appreciate the art more than the first time, to the point that i love it now,
the story is simply perfect, so interesting, with a well build background, and, even with lots of action i can't call it shonen,
usually i hate story with child protagonists, but enzu is the best!, and iremi is...mmh... i don't know, i'm waiting the 3° part (and edermask forever)
about corean works, there a shonen that i find fun: noblesse, so much posing, with those people fighting in those attire, really a continue lol
