I don’t like the change you’ve made to canon regarding Hiashi having access to a giant chakra tap. If he did, Toneri would have targeted him previously. The caged bird seal prevents the eyes from being stolen and has a control seal so the main branch can cause pain or even kill a branch member. There’s no other functionality like what you’ve introduced (allowing Hiashi to absorb the chakra and life force of hundreds of Branch members). You basically turned Hiashi into Voldemort. Part of the fun of a self-insert is being able to have knowledge to power up and beat the world using your knowledge as cheat codes. When a self-insert fic suddenly changes things to canon unnecessarily (like Toneri coming early, Hiashi is now an evil dark lord willing to suck the life out of hundreds of his clan members for a 3 minute fight, a new female Uchiha magically appears, etc.), it kind of takes away the magic of the story. TL;DR: What’s the point of being a self-insert when so much of the world is different from the SI’s memories? I enjoy your story otherwise. It’s well-written and entertaining. If you kept the world canon without power scaling the world to meet the MC as a challenge, it would have been much better.
