Kishin Douji Zenki
for short) was a fantasy action manga/anime by Kikuhide Tani and Yoshihiro Kuroiwa that appeared in Monthly Shonen Jump from 1992 - 1996.
There was a priest called Ozuno Enno who controlled Zenki 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
- Apocalypse Maiden: Inugami, in the anime.
- Brainwashed and Crazy: When the Karma seeds latch on a human, this is their primary effect before forcibly mutating them into monsters.
- 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 and Amon the puppet master.
- Butt Monkey: Zenki, as a kid.
- Dark Action Girl: Anju.
- 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).
- 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, Non-human Dad: Inugami
- 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.
- 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.
- 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...
- X Meets Y: Dragon Ball meets InuYasha.
