Hmm, interesting challenge. I'm not sure if it's possible, but maybe?
"Henge gliders shifts. Hello Kagome. Please do not be alarmed. We are living beings like yourself from another world, one across the Out. We are the ones who are actually responsible for the Uplift concept and all the ideas Hazou has had, and the occasional otherwise inexplicable misunderstanding of social and cultural mores. We're sorry about those, by the way.
"Please put the explosive tags down. Killing Hazou won't get rid of us, we'll just connect to someone else. We're not the weird things from the Out that are relentlessly hostile. We don't like those things either. We helped you fight them and seal breaches, remember? We're not them. We're from somewhere else.
"Much better. Would you like some hot chocolate to help calm down? Our notes say that we have some cups sealed away.
"Where were we? Ah yes, our motivations. Right about now you're wondering how much of a threat we are. We are interfering because seeing the state of your civilization pains us, and we wish to peacefully elevate it to a higher level of development. We are particularly intrigued by the developmental potential for chakra. Our home does not have any. If properly harnessed we believe it could dramatically accelerate your world's developmental path from the one our world experienced. So much technology can be skipped or surpassed.
"Once you're feeling better, could you tell us how seals work, exactly? We've had a dreadful time figuring it out from context. They clearly have absurd potential but it's been dreadful trying to figure out what they could theoretically do if applied to improving everyone's lives instead of the violent applications that ninja are so focused on. Knowing how they work would help us come up with better research objectives for solving the clan's money problems and then moving on to things of wider import.
"Why now? Your description of the memory altering effects of the shifts gave us a way to talk to you directly without Hazou remembering so he would not be unduly alarmed. We don't wish to distress him."
