For the longest time, this bugged the hell out of me, that Usagi had this ultrasonic waves power that she only used the one or two times, but then never again, despite trying to chalk it up to, “Well, Naoko only planned for it to be the one arc, so the powers weren’t that consistent….” It was a decent enough explanation, but it never settled quite right with me.
Until I started really looking at the Sailor Moon story in terms of the themes and its target audience (not that anyone can’t enjoy it! everyone is welcome! but it’s primary audience is girls about Usagi’s age) and thinking of this moment in terms of a young girl trying to figure herself out in a scary and unknown situation.
A young girl who’s desperate in this moment, who’s scared and unprepared for the reality of what she’s facing, of course she’s going to cry and those feelings have power. Sailor Moon is all about a young girl in puberty, growing into a young woman. It makes perfect sense to me that one of her earliest weapons, one of the ones that is most childish (even if it’s entirely understandable, god knows I’d do the same even out of puberty) is a wailing cry that she doesn’t want to be here, she doesn’t want this to be real, she just wants to go home.
How many times have girls her age been through something that’s made them want to cry exactly like this? and that those tears and that crying have an emotional power. It’s something to be outgrown, it’s something that she’ll leave behind when she’s ready to face the situation with more preparedness, that’s just the way of these things.
When viewed through that lens, when it’s the first way Usagi’s power manifested, but later changed because Usagi’s power is all about her emotions and her own manifestations/self identity, it’s something I’ve come to whole-heartedly love about the first time she faces a youma. She’s still barely a young adult, she still has so many childish things about her, of course she’s going to reach for childish expressions! And the whole point of it is that the next time, or the time after that, she’ll be better prepared, because that’s how growing up works.
