Words cannot describe this work of art. It is beautiful, it is imaginative, and it does all of this while being a self-insert fic.
First of all, shut up. Just because it's a self-insert doesn't mean it's bad.
Second of all, Shikako Nara, the author's reincarnated form, is a bloody fantastic character. Not only is she supremely well balanced (talent and skill wise) for a Team 7 Character (characters that tend to fall into Mary Sue
within two chapters of their formation), but Sasuke and Naruto grow realistically and start from positions that actually make sense.
It is a joyous thing to see a fanfic author who has actually thought out her story. And not in the "I have an outline" method, but in the "I have meticulously planned every single constituent detail" method. Plotholes are filled, all aspects of the continuity that may be effected by an OC have been examined and accounted for, and the events that DO happen have an appreciable impact on the rest of the universe in a way not unlike the butterfly effect. It is clear that a lot of time has been spent figuring out what's going on where and when it's going to happen.
Characters are all spot on, and Naruto's annoying obliviousness is played off so well as comic relief that it totally works. Furthermore, the ability of Sasuke to stop being an asshole and Naruto's ability to stop being idiotic while either is in battle is made clear and kept from becoming a one-off deal, as would make sense due to their extensive training in the Academy and, after several chapters, under Kakashi-sensei's tutelage.
Basically, everything is awesome.
Note: As of the writing of this review, the fanfic is still a Work in Progress. Any subsequent increases or decreases in awesome are not accounted for and it is up to the reader to determine how much they are willing to accept this review. Frankly, it seems unlikely that anything less than an increase in the excellence of this fanfic will occur, as the story has been on a constant upward slope since the beginning.
