We publish our audit record because accuracy claims should be checkable. Every entry on this site runs through an automated fact-audit pipeline (accuracy audit → source-grounded repair → visual QA); this page is generated from that pipeline's own report, not written by hand.
This is a fiction/fan codex: entries describe an in-universe canon. Our audits check canon and internal consistency — external fact-checking does not apply the way it does on real-subject codexes.

Rin Okumura — True Cross Academy is canonically located in Kyoto, not Tokyo.
Rin Okumura — Rin Okumura's eyes turn red with slit pupils when activating demonic powers, not blue.
Shiro Fujimoto — STATS: 'Offspring=Rin Okumura, Yukio Okumura' is factually incorrect regarding biology; they are Satan's biological sons and Shiro's adoptive children.
Shiro Fujimoto — DID YOU KNOW: The sword is canonically known as the 'Sword of Kurikara', not the 'Blue Flame Katana'; the blue flames are a manifestation of Satan's power drawn from the sword, not its name.
The Story of the Qliphoth Tree — Satan is canonically designated as the King of Gehenna, not 'Impure King'.
The Story of the Qliphoth Tree — The Qliphoth Tree was destroyed by Rin's flames while the Gate was sealed by Fujimoto; stating the Tree itself was sealed contradicts the canonical events.
The Prophecy of the Blue Flame — Character Name Error: The character's canonical name is Mephisto Pheles, not 'Mephisto Philemon'.
The Prophecy of the Blue Flame — Lore Precision: While Rin Okumura is the primary human wielder of Satan's flames, stating he is the 'only being' is technically inaccurate as Satan himself possesses and uses these flames.
The Rise of the True Demon King — Claim that Satan's power resides within both brothers' souls is incorrect; only Rin Okumura possesses Satan's direct demonic power and the sword Kurikara, while Yukio is a human exorcist without inherent demonic abilities.
The Rise of the True Demon King — Shiro Fujimoto did not die fighting Satan; he died protecting Rin from demons sent by Satan during the attack on the True Cross Church, as Satan remained sealed in Gehenna at that time.
Assiah — The Qliphoth Tree is a central element of Blue Exorcist lore connecting Assiah and Gehenna, contrary to claims it is not found in canon.
Assiah — True Cross Academy is located in Kyoto, Japan, not Tokyo.
Blue Exorcist Shimane Illuminati Saga (2024) — The entry incorrectly states Rin Okumura remains a student trainee at True Cross Academy during the Shimane Illuminati Saga, whereas in the manga canon (Chapter 74+), he has left to work as an exorcist alongside Yukio.
Blue Exorcist Shimane Illuminati Saga (2024) — The entry inaccurately describes the saga's narrative focus as following 'existing students' on a group school-based mission, while the actual story shifts to Rin's independent investigation and the Illuminati conflict rather than a class-led operation.
Ao no Exorcist Original Soundtrack — The claim that 'In the world of Blue Exorcist, sound carries spiritual weight' contradicts established canon; exorcism in the series relies on incantations, talismans, and weapons, not inherent spiritual power of sound.
