The anime *Shinzo* (also known as *Mushrambo*) features characters including Yakumo Tatsuro, Mushra, Sago, Kutal, Mushrambo, and various Enterran antagonists. However, no character named "Rei" appears within the series' narrative, characters, plot, or any official *Shinzo* media such as seasons, movies, or spin-offs. References to "Rei" found elsewhere pertain solely to Rei Ayanami from *Neon Genesis Evangelion* or the "Rei Ayanami Expy" trope in other works, demonstrating no connection to *Shinzo*. Consequently, information regarding a "Rei" character in *Shinzo* is absent.
