History Manga / AstraLostInSpace

* RealityEnsues: After [[spoiler:Paulina]] gets taken out of the cryo-pod she was in, she talks to the B5 crew about her learned experiences, discovers some shocking information... and immediately goes right back to sleep from the shock. She's been immobile and frozen for quite a while, so it's expected that she isn't completely back to normal motor functions.
** This also happens to [[spoiler:Kanata after he loses his arm.]] He gives an rousing speech to the crew that motivates them... and then immedately falls to the floor [[spoiler:due to lack of blood and his stump still hurting.]]

* RaisedAsAHost: [[spoiler: The entirety of Group B5 were raised to be new bodies for the people that they were cloned from.]]

** Having caught wind of the impending plot to kill the group, [[spoiler:the cousin of the King of Vixia]] got Aries added to the group. Not only she's the one who comes up with how to come back home in spite of the ship being able to carry supplies for twenty days at a time, [[spoiler:[[SpannerInTheWorks her very presence makes Charce less willing to go through with the murder plot]]]].

* TheNamesake: The title of the series comes from the spaceship they're traveling in, dubbed the ''Astra'' by Kanata. [[spoiler:Astra is also the name of the B5 team's home planet.]]
* NoBiochemicalBarriers: While the crew of the Astra does have to check food for edibility, the process is treated more as if they were simply unfamiliar Earth plants rather than completely alien ecosystems. Every planet they visit has Earth-compatible chemistry; up to and including toxins that have the same effect on humans as the local wildlife.

* BeachEpisode: The crew's trip to Arispade serves as one. As far as planets went so far, Arispade was the least openly hostile and had resources to spare, letting everyone breathe for a while and the girls to [[{{Fanservice}} have their fun in swimsuits]]. At least, until Luca and Ulgar's respective family dramas come into play.

* AlwaysSomeoneBetter: A comedic example in the final volume's omake. Quitterie released a moderately successful diary of her experiences in space, only to be beat out by Zack's novel. ''That'' is beat out by Charce's lifeform paper, but all of their books' popularity combined can't hold a candle to Yun-Hua's gravure magazine.

* AspectRatioShift: The anime is typically presented in a letterbox format, though will go into full-screen shots during either dramatic or space-focused moments.

* SportsDad: * Kanata's father is one. Being a decathlete himself, he wants Kanata to enter in the sports field as well, preying upon Kanata's wish to become strong in order to get the sportsman he wants. His attitude is explained away with [[spoiler:the reveal that Kanata is his father's clone, and dear old dad plans on bodyjacking Kanata to relive his glory days as a youthful athlete.]]

* CerebrusSyndrome: Downplayed. [[spoiler: While the series never loses its idealism and ultimately has a happy ending, the more fun-loving, planet-exploring first half is drastically different from the dramatically inclined and conspiratorial second half.]]

* CerberusSyndrome: Downplayed. [[spoiler: While the series never loses its idealism and ultimately has a happy ending, the more fun-loving, planet-exploring first half is drastically different from the dramatically inclined and conspiratorial second half.]]

* OutgrownSuchSillySuperstitions: [[spoiler:In this timeline at least, the Astrans don't have a concept of God anymore after a century passed.]]

* CerberusSyndrome: Downplayed. [[While the series never loses its idealism and ultimately has a happy ending, the more fun-loving, planet-exploring first half is drastically different from the dramatically inclined and conspiratorial second half.]]

* WhereAreTheyNowEpilogue: The final chapter serves as some minor resolution to the main cast's character arcs, then skips ahead to seven years later. [[spoiler: Charce is now king of Vixia, Yun-hua is a professional singer, Funi is now attending the high school where Paulina happens to be a teacher, Ulgar became a journalist like he wanted (often crashing at Luca's), and Aries got engaged. Kanata, Zack, and Charce go adventuring through space from time to time, as well.]]

** Rather justified, since [[spoiler: the series is set in the future, and who knows how weird names will be by then.]]

* DeathWorld: Icriss. No matter where you go on that planet, you're going to have a tough time there. The half closest to the light is barren and dry, the half farthest away is cold and unrelenting, with the habitable middle plane filled with aliens that evolved to kill each other.

* ArtisticLicenseBiology: [[spoiler:Luca, despite being intersex, is a full {{Hermaphrodite}} with both working reproductive organs. While this somewhat lines up with his originator's intentions of making him a perfect blend of gender, real intersex people's genitalia come in a variety-- those whose parts show up as one or the other, those with genitalia that looks ambiguous, and those who appear outwardly one sex but have the opposite sex's characteristics inside. There were never cases of intersex individuals having both parts. But since Luca is a genetically engineered clone, it's justified.]]
