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.

Karma Akabane — The claim that Karma assaulted his 'homeroomer' is a factual error because the term 'homeroomer' refers to a student who shares a homeroom, whereas Karma's target was Koro-sensei, his teacher.
Tadaomi Karasuma — Karasuma is incorrectly listed as a 'Homeroom Teacher' instead of his canonical role as Government Liaison/Supervisor.
Tadaomi Karasuma — Karasuma's background designation is incorrectly described as 'renowned assassin' rather than elite Agent/Special Forces Operative of the Ministry of Defense.
Gakuho Asano — Backstory Error: Asano was placed in Class E by his father as a deliberate educational experiment/pressure tactic, not demoted due to personal tragedy.
Gakuho Asano — Motivation Error: Asano assists Class E because he recognizes their value as Kunugigaoka students, not with the intent to disprove his own meritocratic philosophy.
Japanese Government — The Japanese Government orchestrated a national program with global stakes, rather than a 'global assassination plot' (other nations attempted independent assassinations without being orchestrated by Japan).
Japanese Government — Canonical affiliation is primarily the Ministry of Education (Special Assassination Division) coordinating with Self-Defense Forces; 'Defense Task Forces' is not an official proper noun for their organizational structure.
Class 3-E — The letter E officially stands for Ends -> In canon, 'E' simply denotes the lowest academic rank in the school's tracking system (following A-D), not an acronym for 'Ends'.
Class 3-E — standard anti-sensei weapons like BB guns -> Students are issued specialized firearms and blades made of specific anti-sensei materials; standard BB guns would be ineffective against Koro-sensei.
United States Assassins — The entry incorrectly identifies Takaoka Akira as 'The Reaper' and a US operative; canonically Koro-sensei was 'The Reaper' and no such character exists in that role.
United States Assassins — The entry falsely claims international/US scientists developed Anti-Sensei bullets; they were developed exclusively by Dr. Shinjiro Hara's Japanese team.
Shiro's Lab — The entry incorrectly identifies the subject of Shiro's experiments as a 'human assassin' when canonically it was Maaya's homeroom teacher, who was kidnapped and transformed into Koro-sensei.
Shiro's Lab — The claim that Shiro and Koro-sensei face off in 'multiple subsequent battles throughout the main series timeline' is inaccurate; their confrontations are limited to origin flashbacks and a single encounter near the final arc.
Gakuho Asano — The claim that Gakuho Asano demoted a student to Class E simply for being 'average' contradicts canon mechanics; students are sent to Class E specifically for falling into the bottom academic rankings (bottom 10%) or having behavioral issues, not merely for be
