In the Eikan-ki, the line “To make the Hattori clan descendants of the Qin clan is wrong” should previously have been not the Hattori clan but the Aoyama clan.
The "To regard the Hattori clan as descendants of the Hata clan (an ancient immigrant clan) is incorrect" in "Eikan-ki" (a medieval chronicle) should, previously, not have been the Hattori clan but should have been the Aoyama clan. Also, an unfamiliar family crest called "Aoyama Namimon" (a kamon motif of waves) has appeared. ○ "Naoe Kanetsugu" should have been "Naoe Kanetsugu" with the "tsugu" written using the character meaning "inherit" rather than the one meaning "continue". In January 2024 it suddenly changed. Also, Hideki Tojo was, for a time, altered from the spelling with the old-form "jo" to the simplified "jo" and was being talked about as the Mandela Effect, but now it seems to be a "revert" Mandela Effect and has gone back again to the old-form spelling of Tojo.
This case is part of the Mandela Effect case database based on "The Window of Opportunity: A Guidepost to the Mandela Effect — The Ultra-Secret X-Files" by Aoyama Takuto.
