She does actually file them down in at least one episode. But they soon grow back.
yeah, one. we needed more scenes like that. if they do grow that fast, then we should've seen that she takes care to file them down. especially since the writers are so hung up on 02 desiring to be human. but naw, let's waste time with characters like zorome, and miku, and ikuno, and futoshi, who honestly, add nothing to the entire narrative. i'm so invested in futoshi's eating disorder, which was brought, and dropped, in a single episode. at the very end of said episode, mind you. remove these four characters and you lose nothing from a narrative stand point.
