|This article is about a/an ally(?) in Kamen Rider Zi-O.|
In 2022, Master Gamano saved Rentaro Kagura's life and gives him a gourd and its power to transform into Kamen Rider Shinobi. He lives with the Kaguras in their house and is often consulted by Rentaro regarding matters. Due to him being disguised as a frog in a wall scroll, Iroha is not aware of his presence.
Behind the scenes
Master Gamano is portrayed by Nobuo Kyō (姜 暢雄 Kyō Nobuo), whom previously portrayed Einosuke Mido/Kamen Rider Amazon Neo Alpha in Kamen Rider Amazons: The Last Judgement, as well as Isshuu Kasumi/KuwagaRaiger, a ninja Sentai hero in Ninpuu Sentai Hurricaneger.
His name is play on "Master of Toad" (蟆の師匠 Gama no Shishō).
- At the end of the last episode of Rider Time: Kamen Rider Shinobi, Gamano's ally status becomes questionable, since he revealed that he is actually using Rentaro as a "sacrificable object" similar to Sou Fueki in Kamen Rider Wizard.
