Ore-tachi ni Tsubasa wa Nai: Under the Innocent Sky starts in Yanagihara City, where three stories playing out in parallel. The first is Takashi Haneda, who has to deal with his little sister Kobato and Asuka Watarai, his girlfriend...maybe, all while dreaming of a fantasy land called Gretagard. The second is Shusuke Chitose, a freeter who's pals with Karuo Karube, the bartender at Alexander, a restaurant where he's in an unsteady relationship with a fellow employee, Hiyoko Tamaizumi. The third is Hayato Narita, who's captured the attention of Naru Ootori, younger sister of his acquaintance Kakeru, who's looking for her bike. What do these three have in common? Overseen by the mysterious DJ Condor, a story begins.Originally a Visual Novel by Navel (SHUFFLE, Soul Link), Ore-tachi ni Tsubasa wa Nai (We Don't Have Wings), was adapted into an anime in spring 2011.The anime can be legally viewed at Crunchyroll hereand on Funimation's Youtube.
Art Shift: Occasionally, episodes will transition to a different art style than the one shown, most often a still of the background in Deliberately Monochrome. Episode 12 runs with this, but makes crayon drawings horrifying.
Ax Crazy: Garuda Darkblack, also known as Itami Karura. He's the fourth personality.
Badass Bystander: Hayato is this compared to the two groups fighting each other.
Bandage Dude: Itami wears one because Kakeru sees Itami as Falcon aka Hayato.
Black Dude Dies First: Averted with Martinez, Hayato's friend. He's also not the first person to get shot either, although he's the only one with a serious enough wound to be taken away by an ambulance. He survives the shooting, and can be seen in later episodes doing okay.
Book Ends: The first omake has the main girls in love with the main character, all trying to grab his interest. The ending shows all of the same girls falling for the Haneda's personalities. It's the exact same animation, but with slightly different dialogue.
Cast of Snowflakes: There are a lot of named characters. In fact, the OP shows off every major character.
This trope is apparently as accurate as you can get when comparing the dream world and it's real counterpart Wing Quest. All of the dreams are fake, since they were based on the game Haneda played as a child, and translated to one of his personalities.
Five Lines, Overflow: By reading the description at the top, you would assume that all of these "timelines" are all separate from each other, which they are. That's not the point here: all of the timelines are done at different points of the same day, by the same person. That "Gretagard" sequence, however, is fake.
Gainaxing: You can average the times the anime does this to around 1 Misty May per minute.
Genre Busting/Widget Series: It gets hard to classify this after Episode 4. Episode 7 shoves that in a cake and throws it out the window. Episode 12 is completely different from everything else.
Gratuitous English <-> Gratuitous Japanese: One of the rare justifications for both tropes. Alice is trying to learn Japanese, but, as noted by Hayato, her grammar is still off. Over the course of the anime, she improves.
Omake: The two minutes of pre-credits action is not part of the main story; each one is a completely different genre of anime. That does not mean the omakes aren't important, since they act as Foils to the main story.
Split Personality: Takashi, Shusuke and Hayato are revealed to be the same person. There are also hints of a fourth one as well. Said fourth is crazy.
The anime does a fairly decent job hiding this fact. While everyone in the show saw the same person, viewers see what appears to be different characters, which makes sense because each split personality would view themselves differently. There are clues sprinkled throughout the anime that hints at this, such as when Shuusuke gets hit in the back of the head with a chair, and then both Takashi and Hayato have the same exact wounds later on.
Talking to Themself: The three personalities are aware of each other, and if necessary they meet in some Pocket Dimension that resembles a church. And it seems they work in specific shifts according to the one and only conversation two of them have had so far. They also refer to their host body as a "cockpit".
And if the opening is to be believed, the five personalities aren't exactly the only ones who exhibit this trope.
Theme Naming: Birds are the motif in this show, in names, titles, everything.
Title Drop: Dropped by Takashi in episode 8. And then repeatedly in 11 and 12.
Tomato Surprise: The fifth personality, Haneda Youji, is the original personality of the "cockpit", who was in a Angst Coma (in the form of the place with the TV) since the death of his mother. The others were "created" so that Kobato could be cared for.
Tsundere: Asuka, who's not afraid to beat up Takashi or his split personality counterparts.
Updated Rerelease: Oretachi ni Tsubasa wa Nai R, which adds two new routes and a couple new CGs.
