This book was so weird and yet, I enjoyed it. The most random things you can imagine happen, and you do think to yourself, is this really Naruto? The plot is so bad it's hilarious, but once you realise the plot is largely nonsensical and doesn't matter anyway to the larger Naruto canon, you can have a good time reading this.
The Naruto Retsuden light novels are different to all the previous because they all follow the same story like a traditional book trilogy. The first two concern events that lead onto the end of this book and they fit together. Although, I don't think you'd need to read the other two to read this one because you kind of get the gist about what Kakashi and Sasuke/Sakura have been up to. Amidst the strange plot is a lot of sweet moments between Naruto, his family, friends and a scientist who definitely has a crush on him- who can blame her?
The actual story was odd and in the middle I just didn't care about what was going on. Naruto has a chakra sickness because he's a jinchuriki with the chakra of all bijuu in him and the only way to cure it is using polar particles from a meteor the Sage of Six Paths found on his travels in Redaku with his blind astronomer friend. This friend is mentioned a lot but doesn't actually matter to the story much. In the pursuit of this cure Kakashi, Sasuke and Sakura are sent after information and after a successful coup and successfully fighting dinosaurs, they bring everything together. In this book, all the information is sent to Kengakuin, an international research facility with an untrustworthy leader. Of course, trouble ensues because this guy wants to destroy all shinobi for the sake of his nation's (Land of Stairs) economy. A misanthropic scientist is currently doing research in Konoha to turn chakra into other substances so that people no longer need to mine finite resources, which isn't good for Stair's economy because they rely on their natural gas resources.
The motorcycle is invented in this book. Drones try to kill Naruto. Naruto uses scientific goggles which allow him to borrow Hinata's Byakugan. Orochimaru is helping everyone out. Not to sound like a broken record, but seriously? Orochimaru? Not only is he free to complete his weird experiments, they actually trust him to do missions for them. Hell, he was playing with Himawari and Hinata didn't bat an eyelid. He could have stolen her eyeballs and let's be real, those goggles are his attempt to get the Sharingan. Having said that, why was the mum friend role kind of entertaining. Ino and Hinata both say this and I see it. Even though Ino doesn't trust him, she treats him like another parent friend. Orochimaru talking about Mitsuki was kind of cute. And Mitsuki with Yamato was cute too. Even though Yamato rightfully hasn't forgiven Orochimaru (his numerous crimes are indeed unforgivable) he has a sweet relationship with Mitsuki who he probably saw grow up.
I almost loved the ending. It was all about the teamwork with ALL of Team 7, Ino-Shika-Cho, Orochimaru, Gaara and Kurotsuchi. Shikamaru and Chouji are fighting in a nightclub (where Shikamaru's shadows are weak, who knew?) to unlock a guy's phone; Ino and Orochimaru are breaking into Kengakuin to access files to break the seal on the polar particles; Sai is in Redaku to perform the unsealing; Kakashi, Yamato and later Gaara and Kurotsuchi are building a 200km tall pillar to reach a satellite; and Naruto, Sasuke and Sakura are riding a motorcycle into the sky together. It was a strange set of events but I like that we kept switching back and forth between each part of the plan. There were some sweet moments in there and some funny ones. Naruto wedged between Sakura and Sasuke to witnesses them kissing as he's held in place by Sasuke. They pick ice of each other like monkeys picking fleas. It was wonderful imagery. Of course, they succeed at the final moment.
The most interesting and frustrating part of this book was just seeing these characters as grown ups and how their friendships have developed. Little snippets of Shikamaru and Chouji crying at Ino and Sai's wedding, Naruto and Hinata watching Icha-Icha-Paradise on a date, Neji's diary, Hinata and Sasuke's little "chat"where she basically threatened him, Boruto being a good big brother, Himawari being cute and the depth of Naruto and Sasuke's bond. This guy, rightfully so, was willing to give his life for Naruto. Do I have to forgive him now? They're still fighting though, and just like before its because of that bond they have. Naruto's interactions with Chihare were a real joy as well. In the face of this woman who doesn't think she needs others and is amazed by Naruto's ability to draw people to him, Naruto reflects on the happiness at finally having people around, has brought him.
To be honest, I would have loved this book if it didn't have the absurd plot and it was just these friends interacting. The story was almost extraneous. That being said, I enjoyed the ending and it did facilitate what I liked about this novel. I just wish for more domestic, peaceful bliss for the Uzumaki's. And can we finally, after all the damn light novels they mentioned this in, change the bureaucratic processes of Konoha so Naruto and Shikamaru can get some rest please!
An absurd ending to this absurd trilogy. But it was cute to see our favourite characters as adults so I'll accept it as mediocre, but fun, fanfiction. It was the best of three.
