|“||I...made a mistake...!||„|
|~ Futakuchi-Onna's final words before her death.|
Yokai Futakuchi-onna is an antagonist in Shuriken Sentai Ninninger. She is a glasses/negotiator-themed Yokai that was created by Masakage Tsugomori. Her introduction credit also calls her "Two Mouthed Woman Futakuchi-Onna".
She was voiced by Miyuki Sawashiro
Created when a pair of glasses infected by Masakage's Sealing Shuriken, Futakuchi-onna was tasked by him to gain control of one of the OtomoNins. She suggested that the Ninningers may be targeted as well but her idea was rejected and Masakage threatens to destroy her if she dared to disobey her orders. After getting Rodeomaru under her control by making him sign her contract, the OtomoNin assisted a Giant Yokai Gashadokuro that attacked Shuriken Gattai Shurikenjin and targeted Kinji to control him. Yakumo and Kasumi tried to negotiate with her and with Kasumi's tricks, Futakuchi-onna was tricked into freeing Kinji and Rodeomaru from her controls.
Enraged by the betrayal, she tried to battle the core five Ninningers but in the end, defeated by Ninja Ichigeki and was not revived into a giant by Kyuemon Izayoi in the end.
Futakuchi-onna was among ten Yokai who appeared alongside Kyuemon Izayoi and the Western Yokai Wolf Man to Kinji in his vision after he had transformed into reincarnation of the Wolf Man, all bearing his face. When Kinji overcame his fear and doubt, and thus his Yokai side, he used the Demon Sword Urasame to vanquish all the illusionary Yokai and return to the real world.
Futakuchi-onna acted herself in a similar way to a lawyer/negotiator.
