Y'all realize that was metaphor, right? Hazō is feeling old and world-weary compared to this chirpy little thing and his internal monologue grows more dismissive over time.
Of course you'd say that and the next thing we know is that said person of inderterminate age is rolling 200d100 attack rolls because we were stupid enough to let her get close without dispelling the
metaphor henge.
Okay, serious talk for now:
Some one managed to research skywalkers in that time period and produce enough to kit out Genin.
We don't know this, though. All we know is that this kid - who may or may not be a genin or Mari or someone else entirely - has at least one Skywalker seal. We can't extrapolate from there that other Genins (if she is one) also have them.
I could be wrong but we may be trying to be too clever for little gain here. Lets walk this through:
- In the case of this being Mari, failure to dispel her henge would have which dire consequences? One set of ruffled hairs, two sets of bruised egos and one set of bruised ribs from Akane's bearhug. Either way, nothing we can't afford to lose.
- If she not under Henge, we potentially just punched an allied ninja and barring Noburi being really good at explaining that away ("Riff is a slur in the Mist village and didn't you know that, coming here to pick a fight?") but good luck with that. Chances are, it won't have super bad consequences like Kill Box 2.0 - Raiton Boogaloo since ninjas might understand the whole "henge paranoia" argument, but it won't help our standing either. We don't want Team Uplift to become known as Team Innocent-Girl-Face-Puncher either.
- She is under henge but not Mari. Assuming said person is not friendly, we now have to face someone skilled enough that a) somehow managed to steal the identification codes and b) is within easy melee range of our team. At this point, we'd be better off pretending we didn't notice anything and let said person leave for now. (If the person is friendly, we might get a mild lecture about awareness but nothing too bad, I think.)
tl;dr
The risk to reward ratio is slanted too much in the favor of risk for little gain so while I think we should dispel (it's just best practices to do regularly anyway), we should hold off on punching little girls in the face until we can justify doing so.
