Kamen Rider Datto is a rabbit-themed Kamen Rider appearing in the 8th Reiwa Kamen Rider series, "Kamen Rider Mice," broadcasting from September 2026. She makes her full debut in Episode 2, "The Modern Rabbit and the Running Turtle." Character Overview Transforming Identity: Datto Affiliation: Member of the "Zodiac Alliance" (Rabbit representative), protecting people from mysterious lifeforms known as "Fushigi." Motif: Rabbit Personality/Traits: She is deeply devoted to the leader of the Alliance, Kaburi Minetaka (Kamen Rider Mao). She has absolute confidence in her own speed and constantly measures her time with a pocket watch. Equipped with excellent hearing, she can quickly detect the appearance of the enemy "Fushigi." Combat Style/Abilities She excels at acrobatic hit-and-away tactics typical of a rabbit, utilizing high jumping power and speed. She uses a sword called the "Rabbit Sword" as her dedicated weapon. Due to differences in policy regarding the Fushigi, she engages in a three-way battle with the protagonist, Sora Ozumi (Kamen Rider Mice), in Episode 2. Datto (played by Nanako Ando) is characterized by a sharp gap: despite her elegant appearance, she has a strong-willed and rough way of speaking. Key points of her character and speech include: Rough speech with a gap: While she looks like an elegant, stylish, and trend-conscious modern rabbit, she speaks with a strong-willed, very thorny, and aggressive tone. Obsession with speed and time: Because of her confidence in her speed and constant time-tracking, her dialogue often has a hurried nuance, focusing on time and pace. Attitude toward Kaburi: Because she idolizes the Alliance leader, Kaburi Minetaka, her way of speaking to him is completely different from how she treats others—submissive and full of respect. In the story, she clashes with the protagonist Sora Ozumi (Kamen Rider Mice) using that same aggressive tone in their three-way conflict. To transform into Datto, she combines the Mice Driver with a dedicated expansion buckle and item. Transformation Item (Buckle): "Slash Bone Buckle" Key Item (Egg-shaped): "Ride Eggs 4" She transforms after saying, "Metamorphosis, Henshin." The transformation sound from the driver is: "Rabbit! Kamen Rider! Datto!" By attaching the Slash-On to the Mice Driver worn on her waist, setting "Ride Eggs 4," and cracking the egg via lever operation, the transformation sound for Kamen Rider Datto is activated. Datto's pre-transformation outfit is a retro-modern fusion of Japanese and Western styles. • Clothing: A casual Japanese-modern coordination based on retro Japanese clothing (kimono/haori) paired with a pop-style inner shirt. • Colors/Patterns: Based on bright pastel colors inspired by a rabbit, the T-shirt features catchy font graphics. • Accessories: She wears a "Rabbit Ring" on her hand. First person: I (elegant but sharp) Gender: Female

Kamen Rider Muton is a sheep-themed Kamen Rider appearing in the tokusatsu drama "Kamen Rider Mice," representing the "Sheep" of the Zodiac Alliance. Motif: Sheep (Zodiac) Personality/Traits: She usually does nothing but sleep, but she adores Vanken (the Dog) as "Ken-sama." When it comes to Vanken, she becomes so hot-tempered that even other Zodiac members can't handle her, showing a deeply affectionate side. She has a soft, fluffy hairstyle. Reflecting her setting as a character who is "usually sleeping," she carries an easygoing, sleepy, and "loose" atmosphere. Her clothing features a fluffy, private-clothes-style design that incorporates the "fluffy" image of a sheep into a loose silhouette. It's a warm and cute coordination with a bit of volume and soft textures in the outerwear. Since she is usually sleeping, her speech is also somewhat sleepy, maintaining a slow-paced, relaxed tone. Muton is characterized by her archaic "noja" speech style. While she has a cute side, often seen sleeping peacefully, she uses a refined yet adorable, old-fashioned way of speaking when she does talk. She transforms by saying, "Metamorphosis, Henshin." The transformation sound from the driver is: "Sheep! Kamen Rider! Muton!" When transforming into Kamen Rider Muton, she equips the Mice Driver Bite-On combined with "Ride Eggs 8," which holds the power of the sheep. First person: I (soft/feminine) or refers to herself by name, "Muton," due to her lethargic nature. • Clothing: She wears a soft, loose kimono and haori (Japanese-based) that matches her "sleeping" character setting, resembling a sheep. • Colors/Patterns: Based on white, beige, and calm pale pink. It features gentle, delicate patterns reminiscent of sheep's wool. Gender: Female
