Perhaps, but I don't think she's running tech support all the time. I would formulate what you said the other way round: That Ame is in fact not doing so great in collabs, except for 1:1 collabs with people she is already very familiar with. Group collabs and "new" 1:1 collabs, she is in fact very quiet and reserved there, I do think one can say "shy". And that can be a problem. It was fine during the last one, as the jackbox games' competitive nature gave her something to do without the need to talk much. We could still laugh at whatever the hell she was drawing. But in other group collabs, it's rather notable, and leads to Kiara trying to fill the air. And her 1:1 collabs with JP... well, they are mostly very popular, so maybe it's just me, but they just... kinda... feel rather low-energy to me. And I say that as someone who appreciates Ina's comfiness.
It was an ex post facto thing, yeah, but was it really a Meiji Reformation thing? The impression I got is that it was an Edo era thing, that the Tokugawa shoguns pretended the samurai always had had such an honour codex, and that of course it always revolved around duty and obedience - a very convenient notion for those on top. But of course, already during that era there already were no large wars anymore, and no real "samurai battle" or whatever, so that was in fact a construction. But I think the construction already happened then. Unless I'm mistaken.
