For all of this "Saten should have known better" crap, I have to point something out.
She is a first-year middle school student, which in most cases is age 11-12. She is not a Judgement member with the appropriate training and insight into the world of unsightly things.
As someone who grew up in a major city (and thus had mobility without supervision since that age), I can tell you, your "common sense" is at 'level 1', if even, compared to the level of after college. While in a literary sense, we can draw a parallel between LU and potentially harmful drugs, your average inferiority-complex laden 11 year old will only see the beneficial effects of it.
And finally, the LU is an .mp3. You know what else is an .mp3? Sleep hypnosis and Language learning aids. Which is more reasonable to assume, that an .mp3 could physically harm you, or that an .mp3 can help you do something you couldn't do before?
Edit: Cyrus, I spilled my Pepsi thanks to that, kudos
