If you are fan of Naruto you should definetely read this one-shot, cause it's really good. It basically tells the story of how the "rasengan" was invented and it shows more in dept the bond between Kushina and Minato, and partially also the one between Minato and Jiraya. It's definitely nothing incredible and it won't spark a new series, unlike Bleach's Hell Arc one shot, but it's a nice read and something that could come straight from the original manga (would be nice to see it in a special episode airing on tv, but with the new anime coming in September I don't see itcoming, maybe as a blu-ray bonus for a possible new Boruto/Naruto movie?). The art is the same you saw in the original manga, and that can be both a good and a bad thing, because the panels are really well drawn, but it always feel like an old style, unlike Bleach's and One Piece's fresh style of the latest publications. Still it's pretty neat and a couple of two pages panels at the end are really cool. The only criticism I have for this one-shot is towards the fans (since the decision on who to make a one-shot about was given through fan votes): of all the side characters you literally chose the one with a full flashback arc already in the main series, we could have had something about more obscure characters, I especially have in mind something about Neji that apart from his end was basically absent throughout the entire "Shippuden" part, or maybe something about Killer Bee or Rock Lee, or even something more about Hashirama and Tobirama, since most of what we saw was in the anime and was filler episodes.....
Whatever, this is still a nice little chapter.
Score: 8/10
