The name "Mifuyu" appears in distinct contexts: as a playable character in *Princess Connect! Re:Dive* and as researcher Mifuyu Nakajima in a *Helicobacter pylori* publication. Neither instance connects to *Karura Mau*. Likewise, "Ogura" solely references pianist/composer Miharu Ogura, unconnected to the series. No official *Karura Mau* media—the original manga, 1989 film, 1990–1991 OVA, or subsequent spin-offs—includes this character.
