I remember Hanabi always calls Hinata "Big sister" not directly the name altough their relationship before pain arc is cold but still regarded family feeling I think 🥲
I think the romance toward is good and propper, but I think his attitude to his classmate especially sakura who is his teammate need not to be cold just behave like aphatethic I think. Because they have been years together as classmate and friends 👌
Thanks for the chapter. I think Naruto's hair need not to be red eventough purified bloodline, because blonde hair is Naruto's characteristic and if become red it become Strange 😅
I propose for Naruto create and use concept which chakra can strengthening cell permanently so can make the limit potential higher that would be good ✌
