Similar to other stories claiming that Kidomaru was a child abandoned by Shuten Doji, other accounts of Kidomaru according to texts such as the military tale "Zen Taiheiki" state that he was originally a chigo (a boy kept by a pederast) on Mt. Hiei but that his wrongdoings caused him to be expelled from the mountain after which he dwelled in a cave in the mountains and became a thief.
また軍記物語『前太平記』などによる別説では、酒呑童子が捨て童子であったという説と同様、もとは鬼童丸も比叡山の稚児であり、悪行が災いして比叡山を追われたため、山中の洞穴に移り住んで盗賊となったともいう。
