Naruto: The Guide's Direction

A naruto fan fiction where a guide from outside his universe steps in to preserve kushina's soul to guide him and care for him as a child, while advising Naruto, and providing him with early training and preserving Minato's and Kushina's knowledge for naruto to learn from. The Guide will not make itself known and will instead at the moment of their death present Kushina with the opportunity to take over the ninetails with her soul until it recovers its own(yin Chakra being its soul having been cut out of it by Minato), and provide both of them with a memory space in the seal to leave their last message to naruto, that also categorizes and stores their knowledge of their jutsu. When Kurama's yin Chakra regenerates enough after some years, it will either push Kushina's soul into the seal where she'll meet the guide, or out of Naruto's body entirely and into the afterlife. This will be my first fanfiction so while I'd like to ask for leniency I'd mostly appreciate it if those with complaints could try to articulate exactly what they think is wrong with my novel and why.
