“Revenge had supported me. At the same time, it had eaten away at me. Hatred raced through my body like a poison, and killed all other human emotion. And when I was in that state, he lit the fire in my heart once more.”
Sasuke is one of my favorite characters of all time, and even if sometimes I got annoyed at him and his (reasonable) decisions, I love him as much as I love Naruto. They are my children and the only two characters I care about in the Narutoverse.
However, this novel... well, I have my feelings about it. I hate how Naruto ended, and I don't enjoy any content of the new generation or the new novels or the canon pairings (how Sasuke and Naruto did not end up together is beyond me, but well).
So, even if this was 'supervised' by Kishimoto, I did not think this was my Sasuke. Or my Naruto. I finished Shippuden three days ago, so perhaps I was not ready to read them as young adults, but at the same time, I have the story so fresh on my mind that it's impossible to me not criticize.
— First of all, I hated how the author switched from POV to POV and how suddenly everyone was super supportive of Sakura/cared about her regarding Sasuke's status of not being at the village. Shikamaru said something about it, and Karin even considered sending her the picture of Team Taka to her (and I suppose that's the picture she has in Boruto) and that makes no sense. Karin's love is selfless, of course it is, but I hate how they want to transform her into this sasusaku supporter, which takes me to my next point: Sasuke did not, like ever, mention Sakura on his novel. He did think of his friends, and I suppose that includes her, but he never had any special memory of her and that just proved to me how unbalanced their canon relationship is. In the prologue, he only mentions how Naruto was the only one who did not give up on him and he said explicitly he's only loyal to the village because of Naruto's dream. I hated how she said she was going to be with Sasuke when he came back even if he did not want it because it just proved to me how she doesn't understand him. She never has understood him, and perhaps that's why she's such a docile wife to him. Anyway.
— Sasuke did mention Naruto on his POV, but for the other characters, their relationship wasn't as important. I am not saying Sasuke should base his feelings and thoughts on Naruto alone because I don't see their relationship that way, but there was NOTHING of Sasuke's feelings towards Naruto's actual status or how he lost an arm to save him from the 'darkness'. Everyone acted as if Sakura was Sasuke's most important bond when that's clearly not true (and even as a married couple, I doubt it's true).This would have been better if we had had a moment of Sasuke and Naruto together as friends, and how they moved on with their relationship. But there was nothing. And the fact that Naruto is married already and treats her wife as if she was another of his homies... really, this is a mess.
— No one knows Itachi's true story so Naruto is covering a genocide when Sasuke did express his discontent about it. Naruto became such a pacifist that it even makes sense to him not to use his brain cells (I love him more than anything, but it's obvious his characterization was so bad at the end of Shippuden), but he would never do something that would cause Sasuke distress. It makes, again, no sense.
— That things of the Uchihas loving too deeply and going crazy when they lose what they love... I have no words. Sasuke is someone who has problems opening up to people, but this was not deal with and was brushed aside with something like 'keeping in check his Uchiha blood' (and I guess that's why he doesn't visit the village that often and forgets his daughter, but then again, even if I do think Sasuke loves his daughter and deserves a family, the development of his relationship in canon is problematic at best)
There were many other things like the treatment of Team Taka, but my head hurts at only thinking of this mess. I love Sasuke, and I hope that in another universe he's getting what he deserves or at least a good developed version of what he has in canon.
