The “logic” behind Naruto 689 kakashi getting the perfect sasuno’o is the fact that it’s temporary. It’s a necessary panel for what’s going to happen next. Any real naruto fan would know that kishi does certain things for a reason. This manga wouldn’t have last this long without him.Keep in mind people that the entire reason that Kakashi is able to use perfect susaano is because his chakra is not just his own any more.
Remember naruto can go leaps and bounds because he has two sources of chakra, not just one. So the fact Kakashi could use it makes sense. Besides, obito told Kakashi that it wasn’t going to last, meaning he only will have the sharingan as long as obit co-inhabits kakashi’s body, which in retrospect will only be for this battle. Over all however, it adds an interesting twist to this fight and a long awaited event where kakashi has both sharingan. Good chapter.First as a Sasuke fan Sasuke should do more Naruto gets enough panel and the last 3 chapters better than Sasuke against kaguya. (not saying he is stronger) Kakashi who couldn’t even stand 3 chapters ago is using with ms perfect susanoo. Just WTF he is a disgrace for the Uchiha using the Sharingan. I know obito said that it was temporarily but still. I want Sasuke to kill kakashi and go rogue again just cuz of this ms kakashi.I do like the idea of kakashi getting his sharigan back, but im sensing a lack of people actually not dying in this anime right now. One thing that makes shows/anime successful in general, is when at the right time they let go of certain characters.
Obito should have died a long time ago. I love this anime, but they really are dragging this to much right now. Please end it.
