The shippers were willing to overlook the fish in Naruto's mouth.
Shippu! Konoha Gakuen Den is a Naruto OVA which was released in 2008 as part of the seventh Naruto Shippuden DVD, with its story based on and using the still-cells that were used in Shippuden's second ending credits animation.Set in an Alternate Universe from the main continuity, the OVA (narrated by Sakura, Ino and Hinata) tells the story of Naruto and his misadventures at the high school he attends as a transfer student. From the first day, he swiftly establishes a fierce rivalry with Sasuke, picks fights with every person he can, and fends off gangsters who would seek to defeat him. The story also outlines the three girls' reactions to Naruto's antics, as well as teasing the famous NaruHina ship somewhat.Although the OVA itself is roughly just over eight minutes long, the story shares many tropes with its parent universe, though no hints of ninja activity or tailed beasts are to be found here.You can watch it here.
Tropes present in this work include:
Accidental Kiss: Ino reveals that, the day Naruto transferred to their school, she accidentally witnessed him and Sasuke having a fight. Naruto tried to jump on Sasuke as a fight advantage...only his pants chose that moment to loosen, distracting him...and then there was a LOUD kissing sound.
Naruto:(pulling up his pants) What the hell do you think you're doing?!
Sasuke:(spitting profusely) That's my line!
All Girls Want Bad Boys: Hinata for Naruto, of course. Also, Ino doesn't seem to mind the prospect of being attacked by any of the "hottie" Akatsuki members, causing Sakura to Dope Slap her.
Anachronic Order: The opening scene depicting Naruto and Sasuke's confrontation post-graduation is actually supposed to take place at some point after all the plot threads under the Left Hanging trope below.
Sakura: Starting with the climax? What's up with that?!
Arrogant Kung-Fu Guy: More like "Arrogant-I-Can-Beat-Up-Anybody-Guy," but yeah, Naruto counts. And he's able to back it up, too—in swift succession, he's shown to have taken on Kiba, Lee, Chouji, Tenten, and Neji in combat, and also fought Sasuke sometime prior to that.
Badass in a Nice Suit: Sasuke is shown wearing a jacket and tie during his confrontation with Naruto at the start of the story.
Naruto: All the toughest guys here, step up and fight me!
Ino: Ugh! Honestly, he's just picking fights all over the place!
Breaking the Fourth Wall: The girls are at least aware that the story they're narrating is based on the main Narutoverse's second Shippuden ending. Also, when they're speculating about what the goal of Akatsuki's leader is, Hinata points out that that information (at that time) hasn't yet been revealed in the manga proper.
The Cameo: Many of the main series' major characters get very brief appearances here. Those of note include Iruka, Kakashi, Tsunade, Gaara, Kankuro, Temari, Itachi, Orochimaru, and Kabuto. The other Akatsuki members appear too, but unlike Itachi they are shown as standing silhouettes, and the leadernote implied to be Pain, since he's got the Akatsuki ring on his right thumb, Pain's canonical position is seen sitting alone on a skyscraper girder, himself a good distance from the camera and his Face Framed in Shadow.
Camp Gay: Orochimaru and Kabuto both wear female school uniforms, much to the disgust of the main cast...except Sasuke, who goes after Orochimaru soon afterward.
Dangerously Genre Savvy: The gang leader, looking for revenge on Naruto for defeating him early in the story, realizes he can't beat Naruto in a fair fight...so he and his gang kidnap Sakura, Ino and Hinata and hold them captive, then summon Naruto to their location, then threaten to harm the girls if Naruto tries anything else. Naruto promptly gets beaten up (and Sakura, recounting the incident, notes that he could've easily beaten the gangsters otherwise)...but then the Big Damn Heroes come on the scene.
Date Peepers: Ino leads the others in spying on Naruto and Hinata during their date (observe the image above).
Doing In the Wizard: This universe appears to set aside the ninja elements from the main Narutoverse, including bloodline abilities and mystical jutsus. One striking example of this is Itachi's lack of his perpetual Sharingan eyes, though the eyes he's drawn with here are still very piercing. It doesn't explain, however, why Naruto's eyes take on their familiar Kyuubi look during the attack on him by the gang members (one of the many plot points that are Left Hanging).
Dramatic Thunder: In the opening scene, when Naruto and Sasuke confront each other in a dark field, lightning flashes in the background.
Important Haircut: Sakura is shown doing this at the end of the story, as she was shown to do in the ending credits the OVA was based on. However, there's an expanded reason for the haircut—while Hinata initially thinks it was because of a break-up, Ino's got photos that show something else. Sakura was sleeping on the grass and got gum in her hair.
Left Hanging: The OVA ends with a lot of critical plot threads left hanging loose, although since it's only a short feature, that can't really be avoided. Among the questions it prompts: What exactly leads to Naruto's confrontation with Sasuke as depicted in the opening scene? Why is Tsunade playing Mysterious Watcher over Naruto instead of expelling him for his violence? How does the school survive Tsunade's use of its administrative rights as surety for her gambling loans? What do Gaara, Kankuro and Temari, students from a rival high school, have in store for the protagonists? Does the Kyuubi (or any of the other tailed beasts) exist in this universe, or does the change in Naruto's eyes during his beating by the gang members indicate something else? What is Orochimaru up to and why exactly does Sasuke follow after him? Why is Sai following Naruto around (and does Ino have a crush on him)? Why is this universe's Akatsuki organization tailing Naruto, and what are their plans for the school? What is Sasuke's exact link with Itachi in this universe? What is Naruto's background here, and how does Iruka feature in it?
Mood Whiplash: So Sasuke and the True Companions have defeated the gang leader, Naruto and the girls are safe, Naruto and Hinata go on a date, everything is looking to have a heartwarming ending...and then the news gets grim in informing us that the school's troubles are only just beginning starting with Tsunade having used the school's administration rights as security for her gambling loans.
Superpowered Evil Side: During the gang leader's beat-down of Naruto by his cronies, Naruto's eyes take on the familiar Kyuubi appearance. Sasuke's arrival interrupts what might have happened next, however, and it's never mentioned again after that.
Would Hit a Girl: Considering that Tenten is one of the fighters Naruto challenges, yes, he would.
Yakuza: On his arrival at the school, Naruto declares to his classmates that his aim is to be the Yakuza leader of Japan. They don't take kindly to this statement.
Naruto: My ambition is...to be the soubannote a slang word used by the Yakuza to refer to their gang leaders of all Japan!
Yaoi Fan Girl: Ino doesn't seem too perturbed at Naruto and Sasuke's Accidental Kiss, unlike her reaction when the same thing happened in canon...and she seems to think Sasuke's connection to Itachi is anything but brotherly.
Sakura: We discover the secret relationship between Sasuke and Akatsuki member Itachi?!
