''Brocken Blood'' is a {{seinen}} {{manga}} by Etorouji Shiono.

Kenichi Shurutsu, a 15-year-old high school student of German ancestry living in Japan, turns out to be descended from German alchemist Johan Schultz, whose bloodline confers magical abilities. So his (female) cousin Rena forces him to crossdress, so he can act as a MagicalGirl and fight evil. And make lots of money. [[MakesJustAsMuchSenseInContext No, it doesn't even make sense in context]], but that's OK, because this is a gag-driven parody that runs strictly on RuleOfFunny.

The manga was serialized in ''Young King OURS'' from 2003 to 2012, and is licensed in English by J Manga (digital only).
----
!! This series contains examples of:
* AllPartOfTheShow: Kenichi (as Sakurako) is on a "variety show" TV program, which is broadcasting live. While they're on-air, the villains attack, and Kenichi has to transform and fight. The resulting battle is broadcast to the entire audience, but the viewers think it's part of the program (one viewer is shown commenting "what a weird show"), and it becomes one of their highest-rated episodes.
* AttractiveBentGender: Around volume 3, the author (or his editors) seem to realize that there's a ''certain audience'' for pretty boys in dresses, and start playing up Kenichi's "cute little thing in a very short skirt" appeal.
* {{Bifauxnen}}: Rena sometimes dresses in a gender-ambiguous way, and in those moments would be this, if she weren't quite so buxom.
* BoyishShortHair: Rena.
* BerserkButton: Kenichi ''really'' doesn't like being mistaken for a girl. Unfortunately for him, most of the time he has to keep up the disguise.
* ByThePowerOfGrayskull: Transformations (Kenichi's and other's) are triggered by the GratuitousGerman ''Umgestaltung!''
* ClassyCatBurglar: In her youth, Rena battled the "Impossible Sisters", three chicks in {{Spy Catsuit}}s, who only steal "art created by Bloodline techniques". Of course, by the time we see them, they're old, fat and ugly. [[FanDisservice But still wearing skin-tight spandex.]] Toshio, [[spoiler: the son of the middle sister]], is a WholesomeCrossdresser ClassyCatBurglar InTraining.
* CleavageWindow: Kenichi's original "magical girl" costume, also worn by Asuka, although [[WholesomeCrossdresser neither]] of [[TokenMiniMoe them]] has any cleavage.
* ComicBookFantasyCasting: The appearance of some of the villains is based on real actors; the [[WordOfGod author's notes]] mention Creator/MichaelIronside and Creator/TomBerenger, among others.
* CreepyCrossdresser: Several of the male villains.
* DraggedIntoDrag: Rena likes putting Kenichi into lots of cute (and humiliating) girls' outfits. It must run in the family; Rena's daughter Asuka is very much in favor of seeing Kenichi in drag.
* ExpressiveHair: A lock at the top of Rena's hair stands up when she's shocked, forms into a heart when she's drooling over a hot guy, etc. At one point she refers to it as her "good-looking man sensor".
* FashionVictimVillain: {{Discussed|Trope}} in-universe. Almost all of the villains wear ImpossiblyTackyClothes, and someone usually comments on their costumes.
* FunWithAcronyms: TATU, or "The Tokyo Alchemist Task-force Untouchably", who also hunt evil alchemists but mainly get in Kenichi ''et al'''s way.
* GagSeries: Don't expect anything to make sense, or any plot developments to stick.
* GratuitousGerman: All the magical words.
* IdolSinger: Rena decides that Kenichi, er, ''Sakurako Neushwanstein'', will have this as "her" cover story. The fact that Rena, as "her" manager, gets a fat paycheck from the deal has ''nothing'' to do with it, we're sure.
* IfItsYouItsOK: A surprisingly large number of the villains seem ''quite'' interested in Kenichi, even after they find out he's ''not'' a cute girl. Played mainly for laughs.
* ImpossiblyTackyClothes: Kenichi's original "magical girl" costume, to his great distress, and anything else designed by Rena (but ''especially'' Hanyuu's old costume; he still breaks down at the memories). As well as almost all the other hero/villain outfits. After the fanservice gets ramped up, Kenichi's original costume is usually replaced by {{Stripperific}} versions themed after whatever the context of the chapter is; they still tend to be... unique.
* ImprobableWeaponUser: Kenichi's "weapon" is a huge heart-shaped wand. He uses it as a combination quarterstaff and club.
* ImTakingHerHomeWithMe: Several of the villains try to do this to Kenichi. He's not cooperative.
* IncompatibleOrientation: A three-way pileup. See under Unwanted Harem.
* IncrediblyConspicuousDrag: All the {{Creepy Crossdresser}}s. Also Saionji's bodyguard and her "maid guards".
* InTheBlood: Kenichi, Ai and Asuka get their powers from the "[[TitleDrop Brocken Bloodline]]'', carried by descendants of Johan Schultz, a 17th-century German alchemist who turned himself into a witch [[TheyCalledMeMad to prove his critics wrong]].
* KillerRabbit: Kenichi is an adorable little {{Moe}}-bait thing; as "Sakurako" he's even cuter and more defenseless-looking. [[BadassAdorable He's not that defenseless.]]
* LadyLooksLikeADude: A couple of the female villains, in the "so ugly they look like men" flavor.
* LawyerFriendlyCameo: A couple of "[[Creator/StevenSpielberg big-shot]] Hollywood [[Creator/GeorgeLucas directors]]" make a cameo appearance at one of Sakurako's shoots.
* LongHairedPrettyBoy: Both Hanyuu and Fukano, although they usually look like Long-Haired Pretty Girls.
* MagicalGirl: A parody of the whole genre. Played straight with Ai, Kenichi's little sister, and Rena in her youth.
* {{Meido}}: Kenichi, or rather Sakurako, has to dress like this for some of "her" parts, and some of the CreepyCrossdresser villains wear maid costumes.
* MercurysWings: Kenichi and Asuka's original costume has tiny ornamental wings attached to their heads, over their ears; on their gloves, at the elbows; and on the ''front'' of their shoes. [[ImpossiblyTackyClothes Yes, it looks ridiculous.]]
* MonsterOfTheWeek: A few repeating villains show up and traces of overarching plot starts to develop as the series goes on, but mostly it's "discover new badguys, change into [[MagicalGirl Magical Boy]], kick butt, never see them again" every chapter.
* {{Nosebleed}}: Rena's daughter Asuka, whenever she sees Kenichi in a particularly revealing costume.
* OtokonokoGenre: Only sort-of-kind-of an example of the genre, but the fanservice bump-up is catered to appeal to fans thereof.
* PrettyBoy: Carlo the magician, who causes Rena's "good-looking man sensor" to go off big-time, with much {{squee}}ing. Also Kenichi, Hanyuu, and Fukano, in the rare cases where they're seen in men's clothing.
* RecursiveCrossdressing: Kenichi, as Sakurako, gets a part where "she" plays a boy who is DisguisedInDrag. Everyone marvels at "her" amazingly convincing portrayal. ''"It's as if you actually were a boy who's been forced to crossdress!"''
* SecretIdentity: In a slight switch-up on this trope, the SecretIdentity is the "normal" one, and Kenichi's real identity is the superpowered one. Kenichi ends up with lots:
** ''Meet Sakurako Neushwanstein, Japan's hottest new idol!'' But then Sakurako is tarnished by a (fake) scandal, so:
** ''Meet Kaede Hohenzollern, Japan's hottest new weather girl!'' And he needs another one sometimes, so:
** ''Meet Christine Kouda, cute middle-school girl of mystery!''
* ShoutOut: One of the villains is "Edmund Dorae, famous Japanese-American investor". In the [[UsefulNotes/NamesInJapanese Japanese name order]], that's [[Manga/{{Doraemon}} Dorae Edmund]].
* StrangeMindsThinkAlike: In Chapter 3, both Rena and early antagonist Professor Oonuma independently decide that a pattern of magical energy in the Tokyo region is supposed to resemble a giant portrait of "Shimada ***saku" (probably actor Shimada Kyusaku).
* {{Stripperific}}: Many of Sakurako/Christine's costumes. Played for humor and a gradually increasing amount of {{Fanservice}}. Also several of the {{Creepy Crossdresser}}s, played strictly for FanDisservice.
* TheyCalledMeMad: His contemporaries laughed at Johan Schultz for believing in alchemy. So he proves them wrong by not only mastering magic, but "imprinting" it into his bloodline.
* TransformationSequence: At least once per chapter.
* TransformationTrinket: As originally established, a neck-ribbon. Falls to the wayside pretty quickly.
* UnsettlingGenderReveal: Kenichi-in-drag meets Hani, another MagicalGirl, and more or less immediately develops a crush. The it turns out that "she" is actually Hanyuu, [[WholesomeCrossdresser a boy]]. And working for the other side. Kenichi's much more upset about the former.
* UnwantedHarem: Hani/Hanyuu the crossdressing [[MagicalGirl Magical Boy]] gets a crush on Kenichi-in-drag, without realizing he's a guy; after Hanyuu's revealed to be male, he confesses his love and swears to become a man worthy of "her". And then ''the same thing'' happens with ''another'' crossdressed boy, Fukano. And all three of them end up infiltrating the same (all girl) idol group, with the two other "girls" swearing to protect "her". [[HilarityEnsues Hilarity, of course, ensues.]]
* WholesomeCrossdresser: Poor Kenichi, very much against his will. And then Hanyuu and Fukano. Eventually they start appearing as a PowerTrio on the covers.
