Been reading Solo Leveling for awhile, but something bothering my mind. Those shadows…. are they independent individual who are only the copy/clone of the original beings; or are they simply spirit/soul taken from their death body? If It’s the later, it is a bit disturbing. I mean the others are just monster, but “Iron” was a human. Enslaving a human spirit after his death - rather than let him rest in peace - just doesn’t feel right.
Honestly, it’s in character for him to be this way but you should try to be up front with your kids and support them in their interest. At the very least teach the daughter something for her troubles lol.
