Snow and demons can appoint proxies or be in long distance relationship(not realy far with speed of jinchuriki and shadow clones and there few more ways to get to places fast), 0 tails too many issues to be treat for other countries so there no problems with proper seal.
Land of snow and land of Demons mostly neutral that lean to be allies with Konoha at same time too small or insignificant to make waves, Amaru and Reibi itself not realy well known barely scraping to be tailed beast which it will not become because it have 1 big issue that it's need negative emotions to be somewhat powerful, relative of Daimyo will not cause many problems because she can become political insider for court, as for last one they not realy that close so it's not that important.
Now that i think about it Naruto is prety much harem protag with many girls after him.
Shion(Land of Demons), Koyuki Kazahana(Land of Snow), Amaru(Zero-Tails jinchuriki), Naho(relative of the Fire Daimyō), Chiyo(daughter of the daimyō of the Land of This) and few others including fans of naruto(yes, he has then they are just not shown often and if he said one word they would jump in bed with him).

It also felt strangely... familiar, like I should recognize it despite never being here before. I knew for a fact it wasn't Yomi, nor was it the Land of Shadows and it certainly wasn't Hades. I can't think of any other place that would elicit a familiar feeling from me that also had such a strong sense of Death.

This spell is aplication of mixed fields transfiguration and some others, don't remember specifics.
The most hilarious thing was that the book stated quite authoritatively that the snakes were 'created from thin air.'.

"Opsie. But look! You match with Naruto now!" He gave her a double thumbs up with a wide grin as he tilted his head and innocently asked, "Dattebayo?"
