Muv-Luv Extra is the first of the trilogy encompassing the Muv-Luv visual novels. It tells the story of an average high school student named Shirogane Takeru and his childhood friend Sumika. At the very beginning of the story, Takeru wakes up to find a ridiculously wealthy girl named Meiya sitting next to him in bed, at which point Sumika walks in to wake him up like always. She doesn'ttake it well. The love triangle between these two then proceeds forward and completing both is required to unlock Muv-Luv Unlimited, though there are three other heroine routes and a bad end focusing on the teacher character.'"Extra'' is largely used as setup for the next two parts of the story and thus contains a great deal of foreshadowing. To help set up those two stories, we are introduced to Takeru, the girls he knows, Makoto and Takeru's two teachers, Yuuko and Marimo. Since the story is written primarily to establish Takeru as your standard dense harem protagonist, it wildly embraces every harem cliche it can find so as to contrast more with the latter portions of the story. Hidden beneath the childhood friends and wacky hijinks are a surprising amount of little details that do not become relevant until far later in the story as a whole.See Muv-Luv for the other works in the series. The story is directly continued with Muv-Luv Unlimited.
Bleached Underpants: The all-ages versions of the trilogy censor the H-scenes. The 2012 PC re-release of the original trilogy is 18+ though, as it was intended to be a support release for newer Windows versions.
Book Ends: The ED of the prequel Akane Maniax, the OP of Extra, and the ED of Alternative, is the same song: "Muv-Luv" by Minami Kuribayashi.
Takahashi Ichimonji, Meiya's limo driver, is basically RyousukeTakahashi in personality and traits - stoic, always with a laptop, formulating a Theory of Maximum Street Velocity - with the face of Takumi Fujiwara.
Pay no mind to the fact that Meiya looks very similar to Mitsuki and Sumika looks similar to Haruka or that Sumika gets hit by a car in "Extra" in blatant reference to Haruka's accident in Kimi Ga Nozomu Eien. Don't worry, this is only played for laughs and Sumika gets better pretty much immediately. As you might have guessed, like Haruka and Mitsuki, Sumika and Meiya are the main heroines in this game. As a bonus, the song "Muv-Luv" is sung by Haruka's voice actress and is apparently, by "Word of God," a song about Sumika. To make up for it, the personalities between Meiya/Mitsuki and Sumika/Haruka are completely different.
Fan Translation: Muv-Luv Extra, Unlimited and Alternative were translated by Amaterasu Translations in 2010 and 2011.
Foreshadowing: Many events and characterization in Extra heavily foreshadow events in the Unlimited and Alternative worlds, such as Miki's incredible ability with archery.
Intended Audience Reaction: Extra is really meant to be painfully generic. If it wasn't, the overall premise of dropping a generic harem protagonist into a battlefield would not work. Similarly, negative reactions to the characters in the first part are also setup, such as Takeru'spersonality and upbringing working extremely poorly in the world that Unlimited and Alternative take place in.
Insult to Rocks: When Takeru calls Sumika a slug, she gets so angry that she accidentally does this to herself:
Sumika: Gaaaaah!!! Apologize to slugs!
Takeru: Gyahahahahaha!! do you even know what you're saying!?
Road Cone: As the direct sequel of Akane Maniax, Mitsuki's end in Kimi Nozo is canon to Extra.
Schedule Slip: Extra, Unlimited and Alternative were supposed to be released together, but Alternative got delayed for three years due to various problems, thus the Japanese meme "Oruta mada~?" ("Is Alternative here yet~?").
Seinen: Despite running in Dengeki Daioh, the manga adaptations of Extra, Alternative and Total Eclipse are classified as such.
Silent Scapegoat: Ayamine's mother, who, as a nurse, chose to take the blame for Dr. Sagiri's malpractice.
Super-Deformed: In typical âge fashion, characters are drawn as such during moments of levity, as well as in Sumika's diary sketches (see the image on the YMMV subpage for an example)
Trademark Favorite Food: Ayamine's yakisoba bread, as can be seen in this page's picture. During the cooking contest on her route, she potentially beats out the other girls' highly elaborate dishes by making the best possible yakisoba bread.
