Kishin Douji Zenki (or Zenki for short) was a fantasy action manga by Kikuhide Tani and Yoshihiro Kuroiwa that appeared in Monthly Shonen Jump from 1992 - 1996. A 51-episode anime adaptation aired on TV Tokyo in 1995.
There was a priest called Ozuno Enno who controlled Zenki and other powerful demons to defeat the demon goddess Karuma. A thousand years later, when Karuma and her minions return, Zenki gets summoned by Chiaki Enno, a pigtailed Miko who is Ozuno's descendant.
Zenki and Chiaki now have to put up with each other and fight demons at the same time. The only catch? Zenki's been forced to become a little kid every time there's no threat around. So now he's gotta hang around Chiaki during her school days, as Karuma's threat expands around them...
Kishin Douji Zenki contains examples of:
- Action Girl: Kazue. Anju was one in training before being brainwashed.
- Action Survivor: Chiaki and Sayaka
- Adapted Out: Quite a few characters either never show up in the anime or got replaced by anime exclusive ones.
- Alien Blood: people possessed by the seeds bleed green.
- Alternate Continuity: The TV series can be considered this since despite the similarities it deviates heavily from the manga, and the entire 2nd half of the TV series note is anime only, the OVA by contrast more closely follows the manga.
- Apocalypse Maiden: Inugami, in the anime.
- Big Eater: Zenki, in his child mode. When possessed by one of Karma's Seeds, the Principal of Chiaki's school (normally a Reasonable Authority Figure) goes Villainous Glutton mode.
- Bishōnen: Zenki, Akira/Gouki, Inugami and Amon the puppet master.
- Bloodier and Gorier: The manga is a bit bloodier than the anime.
- Brainwashed and Crazy: When the Karma seeds latch on a human, this is their primary effect before forcibly mutating them into monsters.
- Butt-Monkey: Zenki, as a kid. He kind of Deserves it though.
- Canon Foreigner: A very significant number of characters are exclusive to the anime note , which actually result in a number of differences from the manga.
- Dark Action Girl: Anju.
- Demon Slaying: What Zenki has been summoned to do.
- Dirty Old Man: Jukai, who among other things, gets very excited about being asked to rescue a bunch of nude woman from being trapped in a giant spider net.
- Eyes Do Not Belong There: The first monster Zenki faces after he gets summoned in the manga is actually two guys, joined together by an eye and a membrane.
- Fanservice: Chiaki's panties are kinda obvious from time to time. When she's in a skirt, that is (which is relatively frequent in the anime).
- Also, Anju is a Dark Action Girl with a great figure and killer legs.
- Ghostly Goals: One episode of the anime deals with the ghost of a samurai being affected by its past and a Karma seed...
- Gold Fever: The first monster Zenki faces after he gets summoned in the manga. The guys came to Shikigami Town to summon Zenki and make money out of that. Another enemy in the anime is obsessed with money and transforms into a monster that turns everything into gold; Chiaki is forced to strip to her underwear when her clothes start turning.
- Human Mom Nonhuman Dad: Inugami, although this is mostly in the anime
- Leeroy Jenkins: Zenki, who always tends to rush his opponents even in his child form.
- Ordinary Highschool Student: Chiaki, until the adventure starts. Ako and Sayaka are more genuine examples.
- Power Limiter: Chiaki's bracelet keeps Zenki in his Sleep-Mode Size.
- Raised by Dudes: One of the biggest difference between the manga and the anime? In the manga Akira/Gouki lives in a religious all male village, and he's mainly referred to as "Gokimaru" rather than "Akira" like in the anime.
- Red Eyes, Take Warning: People infected with the seeds, Zenki himself to in his true form.
- Religious Bruiser: Souma Miki
- Sleep-Mode Size/Shapeshifter Mode Lock: Zenki's child form.
- Star-Crossed Lovers: Anju and Souma, since she was brainwashed into following Karuma when a teenager and forgot that Souma was her Victorious Childhood Friend... only to die in his arms few after she manages to remember. Later Sayaka and Inugami, doubling as Inter Species Romance. Both of these are exclusive only to the anime.
- Tamer and Chaster: The Latin American version of the anime was toned down in various scenes which shown Full-Frontal Assault, changing and extending other scenes, since the anime was adapted to be emitted for younger audiences during the "anime fever" of The '90s.
- Transformation Sequence: Whenever Zenki turns into his true form
- Truer to the Text: The OVA is closer to the manga than the TV series was.
- Was It All a Lie?: Souma tries to give ask this to Anju in the middle of a What the Hell, Hero?. His harsh rebukes actually start undoing her amnesia and her brainwashing...
