[[caption-width-right:350:Dokkoi!!]]

Suzuo Sakurazaki has just come to the big city for college, but he needs a job. When Tanpopo, a green-haired little girl representing a toy company, offers him a belt that will transform him into the superhero Dokkoida, Suzuo mistakes the whole thing as an advertising gimmick. He realizes too late that it's for real, and toy companies can make weapons, too.

Tanpopo's company and a rival are, in fact, competing to market their super suits to the galactic police. Whichever one is proven more effective will gain a contract for mass production. To test them, the police have unleashed three powerful supervillains and promised a full pardon to whichever of them can successfully unmask our heroes. Everyone is provided Secret Identities, which if found out would render the entire test null and void. Despite this, budget constraints force everyone to be placed in the same apartment building.

And so Suzuo and his "new" little sister "Kosuzu" come to live at the Cosmos House apartment, befriending their (strangely familiar) neighbors while fighting for truth, justice, and winning the contract.

Originally written by Taro Achi as a six-volume light novel series (with illustrations by Yu Yagami), '''''Dokkoida?!''''' also has a three-volume manga (written and drawn by the same pair, released in English by CMX) and a twelve-episode anime series (released in English by Creator/{{Geneon}}) following the antics of the residents of Cosmos House both on and off the job.

!!Tropes:

* ActionGirl: Asaka/Neuroloid Girl
* AllMenArePerverts: Parodied when all it takes is a soap opera episode to convince most of the women of Cosmos House that Suzuo is a sex fiend who wants to get it on with his little sister, and [[DirtyOldMan Marronflower's]] input does ''not'' help.
-->'''Tanpopo:''' It looks like [Suzuo] couldn't hurt a fly. I shouldn't judge him by his looks though, 'cause according to even the earliest edition of the Earth manual, [[InvokedTrope all men are basically depraved primates with cell phones]].
* AndYouThoughtItWasAGame: Suzuo
* ATwinkleInTheSky: Happens to Suzuo when he goes overboard welcoming Marilyn Ronmoe.
* BalefulPolymorph: Pierre
* TheBeard: In the manga, Suzuo's grandfather came to drag him back to the family business in the country since he's failing college, but will let him stay for love. Tampopo immediately [[OvernightAgeUp orders aging pills]] to pose as Suzuo's girlfriend. The other women (and Pierre) get more or less the same idea. [[spoiler:Grandpa doesn't buy it, but decides [[TrueCompanions friends]] are an acceptable excuse, too.]]
* BigEater: Hyacinth.
* BrotherSisterIncest: Episode 8, "Little Sister LOVE" parodies this to the point of Deconstruction.
* CowardlyLion: Suzuo.
* DatingCatwoman: Combined with Unwanted Harem.
* DeathbringerTheAdorable: The general end result of Edelweiss's attempts to create fearsome golems.
* DefrostingIceQueen: Hyacinth
* DirtyOldMan: Dr. Marronflower, especially in the anime.
* DoAndroidsDream: The theme of Kurika's ADayInTheLimelight episode.
* DoomedNewClothes: Asaka's yukata.
* FakeMemories: Ruri's family and Suzuo's parents have their memories manipulated to think Edelweiss/Ruri and Tanpopo/Kosuzu are respectively their children.
* GagBoobs: Sayuri, she broke chopsticks with her boobs.
* GeckoEnding
* HappinessInSlavery: Pierre loves his job.
* HardDrinkingPartyGirl: Asaka, preferring beer, really.
* HumongousMecha: Dr. Marronflower's specialty.
* IWasQuiteALooker: Marronflower was quite dashing in his younger days.
* IneffectualSympatheticVillain: Dr. Marronflower, Hyacinth, and Edelweiss.
* InTheNameOfTheMoon: [[JustifiedTrope Justified]] given that the heroes are trying to sell their super-suits.
* KnightOfCerebus: Sweet Pea from the manga; Senator Woodpecker in the anime.
* TheLadette: Asaka
* LethalChef: Kosuzu/Tanpopo; Suzuo eats anyway, both because it's free and to protect her feelings.
* LikeBrotherAndSister: Suzuo and Kosuzu/Tanpopo end up BecomingTheMask in this respect.
* LivingWithTheVillain: Everyone lives at Cosmos House.
* LongTitle: The original Japanese title is ''Sumeba Miyako no Cosmos-sou Suttoko Taisen Dokkoider''
* LovesMyAlterEgo: Hyacinth, Edelweiss, and Neuroloid Girl aren't too crazy about Dokkoida, but each of them harbors feelings for Suzuo in their civilian identities. It's probably significant that this is a reversal of the most familiar expression of the trope.
* MadScientist: Dr. Marronflower
* MagicFeather: See "Theme Music Power Up".
* {{Meganekko}}: Kurika's [[RidiculouslyHumanRobot human form]].
* MoodWhiplash: The last two episodes.
* MundaneUtility: Inverted: The Dokkoida suit has a frightening number of mundane-use "special attacks", which Suzuo eventually learns to use ''in combat'' more effectively than the real special moves.
* NoCelebritiesWereHarmed: Seriously, Marilyn Ronmoe?
* PantyShot: Edelweiss's initial attempt at a dramatic entrance is ruined by this.
* PaperFanOfDoom: Tanpopo's weapon of choice
* PaperThinDisguise: [[PettingZooPeople Petting Zoo Person]] Mogumokuru wears a cheap kabuki(?) mask over his snout to pass as human in the anime.
* PettingZooPeople: A number of the aliens, particularly Captain Mogumokuru (a mole-person) and his boss (a lion-person).
* PrecociousCrush: Ruri/Edelweiss towards Shizuo.
* PunchClockVillain / PunchClockHero: Somewhat literal, as everyone involved receive pay for living expenses.
* RealityShow: One episode has the Cosmos House made into one to defray the SpacePolice's costs. {{Fanservice}} and a HotSpringsEpisode [[HilarityEnsues Ensue]].
* ReedRichardsIsUseless: Averted, an entire episode is dedicated to Dokkoida using his supersuit to make money at various part-time jobs.
* RobotGirl: Kurika/Clicker.
* {{Romanticized Abuse}}r: Hyacinth. Just ask Pierre.

* TomboyishPonytail: Asaka
* {{Tykebomb}}: Edelweiss
* UnwantedHarem: Asaka/Neuroloid Girl, Ruri/Edelweiss, Sayuri/Hyacinth.
