Oni Codexery — Data & Quality

Recent findings (audit lane, verbatim)

Amanojaku — The claim that the Amanojaku is considered the ancestor of the Tengu according to the Wakan Sansai Zue is incorrect; the Wakan Sansai Zue does not state this.

Electabuzz — The entry incorrectly states that Pocket Monsters Blue was released internationally as Pokémon Green; the international releases were Pokémon Red and Blue, not Green.

Electabuzz — The entry claims Ken Sugimori drew all in-game sprites, but they were actually created by other artists like Atsuko Nishida.

Hannya — The entry states that the hannya mask is also called chūnari, but in Noh canon chūnari is a distinct mask type, not an alternate name for hannya.

Hannya — The entry claims that the name 'hannya' first appears in the works of Shimoma Nakataka (1580s–1610s), but the earliest known written record is generally attributed to the 15th-century text *Sarugaku dangi*, not to Nakataka.

Hashihime — The sword Higekiri was not renamed Onikiri after the Hashihime incident; the renaming is traditionally linked to the Shuten-dōji legend, not the Hashihime demon at Ichijō Modoribashi.

Hell wardens — The story of the Buddha being reborn in hell as a wagon puller and killed by a hell warden conflates the Bodhisatta with the fully enlightened Buddha, which is a factual error about Buddhist canon.

Hell wardens — The claim that the Buddha was reborn in the deva realm after this incident is factually incorrect because the Jataka story involves the Bodhisatta, not the historical Buddha after enlightenment.

Ibaraki-dōji — The sword 'Higekiri' is not typically also called 'Onimaru', 'Shishinoko', or 'Tomokiri'; 'Onimaru' is a different sword, and 'Shishinoko' and 'Tomokiri' are not standard alternate names for Higekiri/Onikirimaru.

Ibaraki-dōji — The claim that Ibaraki-dōji was 'Shuten-dōji’s lover, son, or his son's lover' is not a widely-established canon fact; the relationship is typically that of a subordinate, and the 'son' or 'lover' interpretations are rare or speculative.

Issun-bōshi — The claim that the couple 'was disturbed by his size and thought he was a monster, so he left home' is inaccurate; in the standard Otogizōshi version, the couple loved him and raised him, and he left of his own accord to seek his fortune.

Issun-bōshi — The claim that Issun-bōshi 'put rice grains from the family altar into the girl's mouth and pretended to cry, then lied to the chancellor that she had stolen his rice' is a misrepresentation; in the standard Otogizōshi version, he does not frame the daughter f

Kidōmaru — The entry states that Kidōmaru appears in the Kokon Chomonjū, but the story is actually found in the Taiheiki.
