|This article is about an ally in Kamen Rider Decade.|
Yuri Tomoda (友田 由里, Tomoda Yuri) is one of Takumi's fellow students, a member of Smart Brain High's photography club with a dream to create the perfect photo journal.
She is not as good-willed as she initially appears, expressing being prejudiced to the Orphnoch as well as believing Faiz to be an urban legend. However, when targeted by the Lucky Clover members, Yuri learns of Takumi's true nature.
The situation leaves her confused until she sees Takumi attempt to protect her camera, hearing his reason for becoming Faiz. After the fight, Yuri convinces Takumi to keep protecting Smart Brain High to protect her dream.
- Though not a direct counterpart, Yuri can be considered the equivalent of Mari Sonoda from the original Kamen Rider 555.
