I wonder if we can make OPSEC Minatoseals. Like, canon had a whole suite of seals that could mess with what you could say, but mfd's worldbuilding classified that as "advanced biosealing" and had to rule that there was no way for any institutions to reliably do that. But like, what about the special sauce sealing style that lives right in your chakra system?
One of the biggest concerns that always comes up about giving Kagome nice things is that he can't keep secrets and can't learn to keep secrets. I don't mind going ahead and giving him nice things despite that, I think, but it would be a very good olive branch to Naruto on the topic when we return, and put Kagome in a much better position to receive greater secrets, if he accepted Minatoseals that prevented him from speaking about restricted topics in the same way that he relies on the rest of Team Uplift to catch him when they're in the same room.
Or, hmm, maybe just strip out the middleman and try for Minatoseal telepathy. Then, even without Kagome having a minder, there would always be someone "available" ready to send Kagome a cautionary message if the conversation reaches restricted topics. And there are also plenty of other reasons to want telepathic bonds, of course, this way wouldn't just be an imposition on Kagome for the sake of getting Naruto to trust him with nice things. He'd be able to tell instantaneously whenever any of the rest of us are in danger, just off the top of my head.
