History Manga / LinebarrelsOfIron

* KansaiRegionalAccent: Shizuna. It's a coping mechanism for a childhood trauma.

* BladeOnAStick: The Katou groups Arma's carry Spears as a standard armarment, and Sawatari in particular is very good with one (well in his mecha at least).
** Yurianne's Arma 'Tsubaki-Hime' carries a rather stylised version.
** Talisman's weapon, 'Tail of the Kingdom' combines this with a BFS.

* ADayInTheLimelight: Rachel gets an entire [=OVA=] devoted to her; part one deals with how she arrived in Japan for the first time, while part two acts as a semi-{{Interquel}} set between episodes 12 and 13 of the anime.

* CyberneticsEatYourSoul: Subverted with Jack Smith, though his body is an Arma. he is, honour issues aside, a rather normal and somewhat well adjusted individual.

* DeconReconSwitch: This work wastes no time in showing what a terrible idea entrusting a powerful and destructive giant robot to an immature and impulsive teenager is. And then proceeds to show how the same teenager can actually mature and grow to be a real hero.
** For bonus points, we're also shown how the same basic components of this hero -- bullied kid with aspirations of being an Ally Of Justice - can also create either an AntiHero (Moritsugu), a WellIntentionedExtremist (Kiriyama), or an AxeCrazy vigilante ([[spoiler:Miu at the end of her manga arc]]).

* DudeLooksLikeALady: Izuna Endo, twin brother of Shizuna. Kouichi seems to [[Literature/BakaAndTestSummonTheBeasts summon Yoshi Akihisa]] when he jokingly says that Shizuna should act more girlish, then faces Izuna Endo, which ticks her off.

* DudeLooksLikeALady: Izuna Endo, twin brother of Shizuna. Kouichi seems to [[LightNovel/BakaAndTestSummonTheBeasts summon Yoshi Akihisa]] when he jokingly says that Shizuna should act more girlish, then faces Izuna Endo, which ticks her off.

* ArmorPiercingSlap: Risako usually gives one to Kouichi anytime the topic of Emi is brought up.

* {{Gainaxing}}: Almost very female in the anime. Especially during the beach episode. Hayase's arm seems to find its way into their cleavage a lot as well...

* IllBoy: Yamashita prior to becoming Hind Kind's factor.

''Linebarrels of Iron'' is a Japanese manga series created by Eiichi Shimizu and Tomohiro Shimoguchi. The manga was first serialized in Akita Shoten's monthly shōnen manga magazine ''Champion Red'' from 2004 to 2014, and it was compiled into 25 volumes.

''Linebarrels of Iron'' is a Japanese manga series created by Eiichi Shimizu and Tomohiro Shimoguchi. The series was first serialized in Akita Shoten's monthly shōnen manga magazine ''Champion Red'' in 2005. It has since been compiled into 24 tankōbon, as of October 2014.

The Linebarrels of Iron story takes place in a fictional alternate future, centering around a junior-high school student named Kouichi Hayase, who escaped his daily life of being bullied as a child by constantly daydreaming about being a hero. His life was forever changed during a class trip in the year 2016 when an artificial satellite fell from orbit. Due to this "accident", Kouichi was left in a coma for half a year, and upon awakening, found himself with strange powers, including superhuman strength. Then, in 2019, a mysterious robot called "Linebarrel" appears before him. It is revealed that the accident from three years ago was not caused by a satellite, but rather by the Machina robot Linebarrel, and that this turned him into a "Factor", which is the name given to Machina pilots. This leads him to encounter Emi Kizaki, a mysterious amnesiac girl whose unknown past seems to be related to Linebarrel. He joins her in fighting for JUDA, the world's largest medical equipment maker, which happens to secretly own several other Machina robots.

So sayeth Wiki/TheOtherWiki.

Linebarrel looks to play the MechaShow straight to the hilt but Shimizu and Shimoguchi's purpose is a DeconReconSwitch.

* CreepyChild mixed with CreepyDoll: The manga's Human-Machina employ building-sized baby-shaped Machina as ShockTroops, because they're bristling with MoreDakka. It takes the combined efforts of Juda and Katou's team to bring the first few down. Post-timeskip, they're mowing them down by the dozen.

* DeadManWriting: Played for laughs by the anime. When the JUDA crew try to return to the building, they meet a recording of Ishigami stating that it was to be played in the event of his death. Together with a series of increasingly ludicrous ability tests, all of which are introduced with a copy of the aforementioned speech. Lampshaded when they are taken into the InnerSanctum. But it doesn't stop there...

** For bonus points, we're also shown how the same basic components -- bullied kid with aspirations of being an Ally Of Justice - can become either an AntiHero (Moritsugu), a WellIntentionedExtremist (Kiriyama), or a walking MoralEventHorizon ([[spoiler:as Miu eventually does]] in the manga).

* EarnYourHappyEnding: They really have to earn it here in the anime. Expect a lot of TearJerker moments and {{GutPunch}}es before you get to it though.

* IAmNotLeftHanded: Koichi was quite shocked when [[spoiler: Verdant's right eye spontaneously healed itself.]].
** In the manga Emi is content with Kouichi piloting Linebarrel not because he's better at it, as she's a GameBreaker due to being the daughter of the creator of all Machina technology, but because she would literally die from doing it often.

** The [[spoiler: alternate-universe Kouichi and Emi]] which Kouichi and Emi run into in Episode 24 aren't even named outside of SuperRobotWarsL. Their Machina isn't identified either, though it does address [[spoiler: alt-Kouichi]] by a number.

* OvertookTheManga: The anime adaptation follows the manga more or less the same until around the Helios operation, where some details change (both minor and major), then by the time the [[spoiler:Kiriyama coup]] is finished (which does play similar to the manga version with some changes), the anime goes all out on an original ending from that.

** PlotParallel: Usually used for cruel irony. Here we have [[spoiler:Domyouji asking to become the recently-orphaned Shizuna's co-pilot; there we have Sawatari brooding on Abraham Lincoln telling him he has no bearing on the plot meeting Miu who has just crossed the MoralEventHorizon]]. Both are events with the same cause ([[spoiler:Miu killing Izuna, right after he confessed to her, too]]) and similar themes, but vastly different... Well, yeah.

* AllAnimeIsNaughtyTentacles: Episode 12.
* AmbiguousGender: Satoru Yamashita. The anime eventually settles on female, because Satoru's obvious affection for Moritsugu apparently meant [[HideYourLesbians she's a girl]]. Aside from the BeachEpisode, however, where Satoru is portrayed about how a lanky androgynous teen dude would appear in a bikini, the anime upholds the same conventions as the manga: confusing gender pronouns, being immune to both MaleGaze and FemaleGaze as well as all forms of ClothingDamage, [[LimitedWardrobe overlarge untucked shirt, combat boots and bermuda shorts]] and never appearing undressed despite the rest of the cast having been around the {{Fanservice}} block more than a few times.

** BizarroEpisode: Subverted. The BeachEpisode meets most of the qualifications, but it gets a CallBack later and contains a plot-relevant conversation, so technically it doesn't count.

* BewareTheNiceOnes: Izuna uses some of the abuse he suffers against his enemies via the Nerve-crack, resulting in some nasty horror-filled [[{{Squick}} Squickyness]] from the visions sent to anyone affected by it, judging from the resulting screams it's probably a good thing the audience can't see what they see most of the time.

* BewareTheSuperman: Similar to ''Anime/DarkerThanBlack'', sociopathic tendencies seem to be a pretty common side-effect of getting superpowers here.

** Averted with Yajima, but Risako immediately turns him down.
* CanonImmigrant: Several of the anime-exclusive characters and[=/=]or events have been slowly folded into the original manga, most notably Rachel Calvin and Miu Kujou as well as [[spoiler:Yajima becoming Apparition's factor and coming BackFromTheDead]].
** Subverted: These were not anime exclusive in the traditional sense, but pulled from the manga before they were introduced starting so early in the manga's run. The anime used the notes the author had written a long time in advance.

** The scene in Episode 24 of the anime, where Kouichi and Emi [[spoiler: meet alternate versions of themselves inside of a decidedly Dancouga-like Machina]] is very short and feels like a BigLippedAlligatorMoment. SuperRobotWarsL gives them a dialogue scene, which not only [[spoiler: reveals the Machina can talk out loud, and alt-Kouichi's name is [[YouAreNumberSIx R335]], to which he objects, saying [[DoNotCallMePaul he'd rather be called]]... We never hear his response.]] ArcWords are exchanged before the plot returns to its anime rails.

* PostScriptSeason: Episode 26 of the anime is a weird mix of WhereAreTheyNowEpilogue, TheAdventureContinues, StatusQuoIsGod and ends on a BolivianArmyEnding. [[spoiler: With MaybeEverAfter on top]].

* StuffedIntoTheFridge: Yajima [[spoiler:he gets better in both versions)]] Ousei, and Demitri.

* {{Expy}}: [[VideoGame/SengokuBasara Verdant is blue, wields more than 2 swords in each hand, has one eye, and a crescent moon emblem on its forehead]], [[SarcasmMode I wonder who matches that description]].
