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.

Denji — Akane Sawatari appears during the Katana Man Arc (specifically at its climax), not following it as implied by the parenthetical '(following the Katana Man arc)' in the LORE section.
Denji — In Chapter 2, Makima recruits Denji based on his utility and offers him a home/food; she does not explicitly comfort him after he expresses loneliness to her (Denji's primary expressed desire was touching breasts), making the description of their first interac
Aki Hayakawa — Aki Hayakawa was not 'assigned to Denji'; rather, Denji was assigned to Aki as his partner under Makima's orders (Chapter 2).
Aki Hayakawa — The entry labels the lifespan reduction as a 'Contract Cost' in the Stats section. In Chainsaw Man canon, there is no contract between Aki and the Angel Devil; they are partners/colleagues. The lifespan reduction is an inherent trait of the Angel Devil's exist
Kishibe — The encyclopedia incorrectly states Denji and Reze skinny dipped at a school pool; canonically they wore swimsuits at a public outdoor swimming facility during their date.
Yoru — The entry states Asa Mitaka formed a contract with Yoru 'after being mortally wounded', but canonically she was already dead (corpse) when the Fiend contract was established; Fiends require a corpse to inhabit.
Yoru — The entry claims Yoru became 'incredibly powerful when global tensions rose' in the story, which contradicts Part 2 lore where Yoru explicitly states the War Devil is currently weak because humanity does not fear war enough (hence her plan to revive the Nuclea
Reze — Voiced by Reina Ueda - Correction: No official voice actor has been announced for the anime adaptation of the Reze Arc as of now; this is likely fan speculation.
Reze — Second Shonen Jump+ Character Popularity Poll (Volume 10) - Correction: The major popularity polls were held in Volume 8 (Makima won) and Volume 13 (Aki won); there is no prominent 'Volume 10' poll where Denji ranked first.
Yakuza — The entry claims the contract was with the Bat Devil; canonically, the Yakuza boss contracts with the Zombie Devil to hunt Denji.
Hybrids — Katana Man became a Hybrid through heart grafting from his father, not via 'father-son Devil merging'.
Hybrids — Hybrids fuse with Devil hearts or essence; Devils do not possess biological 'DNA'.
Public Safety Commission — The entry claims Kishibe led the Public Safety Commission after Makima; canonically, Kishibe serves as a high-ranking advisor and mentor in Part 2 but does not hold the official leadership position of the organization.
Public Safety Commission — The entry states the organization 'do[es] not establish systems for civilians to create these pacts'; canonically, Public Safety actively facilitates and manages contracts between hunters and devils (e.g., Aki Hayakawa's contract with the Fox Devil) as part of
