If he was able to start leveling deceit or smth I might be more willing to trust him with stuff. But I don't think he's capable.
It's not really on the table, as I understand it. Like, "get Kagome better at OPSEC" is something we've tried many times from many angles over the years, and the result has always been failure, accompanied by QM statements of varying levels of explicitness saying, in short, "this will never happen and Kagome as a character is incapable of it".
If I were to speculate, I would point at the -12 Deceit he rolled against the
[whatever it was] and said he was Kagome Yu instead of Kagami Yusuke. There is a coherent train of thought from there to suggest that "Kagome Yu" as a being is definitionally incapable of lying. Like, literally, the
thing that defines him is lying badly, the baseline truth from which all of Kagome Yu was constructed.
But speculations aside, I do not expect that the N+1th attempt to get Kagome better at lying will finally work this time. An awareness that everyone would dearly like him to clam up about certain topics (when he remembers) is the best passive OPSEC defense we can get. What proves much more reliable is
active OPSEC defense, i.e. having someone else in the room to elbow him before he spills the beans. So imo if we want Kagome to be less of an OPSEC leak, that's the only sensible angle to approach from.
The baseline implementation of it can be somewhat demeaning. Giving Kagome a minder everywhere he goes is a pretty rude signal that we do not trust him on his own, no matter how true it is that we don't trust him on his own or how much he understands that he can't be trusted on his own. I brainstormed a bit, a couple pages ago, on plausible Minatoseal projects to improve active defense, such as an automated Minatoseal that detects forbidden topics and shuts him up, or a telepathic bond by which we could always be in "elbow him before he spills the beans" range without explicitly being a minder. I do not by any means consider that an exhaustive list of ideas, but it's the sort of thing that - if possible - I believe would actually succeed at improving Kagome's OPSEC.
So if we're giving it to Kagome, do we give it to Yuno?
We should probably make sure there's no arcane Isanese prohibition against it. I don't think we'd get hit by something like "my status as a cursed child means I'm not allowed to reproduce, which I believe creating a Shadow Clone would count as" because Yuno has an express intention to have kids when she and Noburi are of age, but far be it from me to assume we know every foible of Isan's (now mostly destroyed) traditions.
But yeah, if she's okay with it I'd teach it to her. We're on our own out here, and for as much as we primarily expect to only encounter Akatsuki-tier threats there's no guarantee what level of combat power we'll wind up needing.
