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...
