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.

Mio — The entry states Blue was '2nd runner up at the Miss California contest that same year' (2005), but widely known records indicate she was 1st runner-up at Miss California 2005, not 2nd runner-up.
Mio — The entry states Blue was '1st runner up to both Miss California in 2006 and Miss Nevada in 2007.' However, widely known records show she was 1st runner-up at Miss California 2006, but she did not compete in Miss Nevada 2007; she competed in Miss Nevada USA 20
Kazama — The entry states Kazama was born on 1 February 1974, but his widely-known birthdate is 1 February 1975.
Kazama — The entry says he was first introduced to drifting at age 17 when he watched Gengo Kitazawa, but the commonly known mentor/sponsor is actually Nobushige Kumakubo, not Gengo Kitazawa.
Chika's Family — The entry states 'Chisa's Family' but the title and text refer to 'Chika's Family' in the prompt header; the correct name is Chisa Kotegawa, not Chika.
Chika's Family — The entry says 'Chisa is already a certified dive instructor and works at Grand Blue' — this is incorrect. In canon, Chisa is a certified diver but not a dive instructor; she works at Grand Blue as a part-time employee, not as an instructor.
Chiharu Minamiya — The entry incorrectly states the character's name as 'Chiharu Minamiya' in the title, but that is a different character; the correct name is 'Chisa Kotegawa'.
Chiharu Minamiya — The entry claims Chisa is a 'local student from Izu who has lived there since childhood,' but in canon, Chisa is from Tokyo and moved to Izu for university.
Kitahara Moves to Izu — The entry states Iori moves into an apartment above the Grand Blue diving shop, but in the canon, he lives in the shop itself.
Kitahara Moves to Izu — The entry claims he chose Izu because it offered both a university program and proximity to dive sites, but in canon, he chose Izu because his uncle's diving shop is there, and he was accepted into the university; there is no indication he specifically chose i
Kotori and Chisa Arc — The entry claims Grand Blue focuses on friendship and comedy over romantic entanglements, but the series includes romantic subplots and harem elements.
Kotori and Chisa Arc — The 'DID YOU KNOW' section states Kotori's surname Inomata means 'inner mouth', which is a fabricated etymology not established in canon.
