The government really should give her a reward or SOMETHING. Since she literally saved all of Shibuya singlehandedly. At least give her permission to take things out of the dungeon as an exception. She's definitely a national grade explorer haha
She really doesn't need that permission though - it is everyone else that is losing out on materials she is otherwise dumping, not her; she can just Divine Artisan anything she wants in situ....
Some of the monsters before that included a doppleganger that can transform into the first person they see and copy their power and abilities exactly. A danger for solos like Karin.
