Kamen Rider Idunn known as Touka Akatsuki was a servant of the Kureshima family and a childhood friend of Takatora Kureshima. Because of her past, she has the unique ability to control the flow of Cracks at will. In an act of revenge, she gains a Sengoku Driver and is able to become Kamen Rider Idunn using the Ringo Lockseed.
Like with the other Armored Riders, Kamen Rider Idunn's forms are called Arms. Her Sengoku Driver plays European trumpet music and announces Come On before every transformation, while her personal Lockseeds are styled in pure English that is sung in a chorus-like manner. By pressing the Sengoku Driver's Cutting Blade down on the Lockseed after transforming from one to three times, Idunn can activate one of three finishing moves based on her current Arms form: Squash, Au Lait, or Sparking.
Arms
Idunn Ride Wear
- Idunn Ride Wear
- The Ride Wear is Idunn's default form undersuit which is briefly seen during Idunn's transformation sequence, before the Armor Part attaches or when she changes Arms. However, this form is completely vulnerable to any incoming attacks when shot at directly in the suit, rather than at the Arms that is descending down on the Rider.
- The Ride Wear that Idunn's Sengoku Driver has is easily identifiable through the Rider Indicator. The Rider Indicator only identifies what Ride Wear a Sengoku Driver contains for simplicity and can be replaced with extensions.

- Ringo Arms is Idunn's default apple-based armored European Knight form, which is accessed through the Forbidden Ringo Lockseed. While assuming Ringo Arms, Idunn dons the Ringo Armor Part and her Arms Weapons are the Sword Bringer and Apple Reflecter.
- As Idunn, Touka was able to fight off against the Kurokage Troopers and even had the advantage against Zangetsu Watermelon Arms. However, this form is still inferior to that of a New Generation Rider and Touka was quickly defeated by Zangetsu Shin.
- This form's finisher is an unnamed Rider Slash: Idunn activates the Squash function on her Sengoku Driver and unleashes a powerful slash with the Sword Bringer. After Touka's death at the hands of Ryoma Sengoku, the Forbidden Ringo Lockseed was given to Kaito Kumon who promptly destroyed it after his battle against the Tyrant Over Lord.
While temporarily in the possession of Forbidden Ringo Lockseed, Touka had these following abilities, following her mutation into Inves. Among them are:
- Crack Creating : Touka can create Cracks freely as means of transportation or sneak attacks. The location of the Crack she creates sometime emits Helheim floras.
- Helheim Plant Manipulation : Touka can manipulate Helheim plant vines freely but never used it as means of attacking her targets.
Devices
- Sengoku Driver - Transformation device
- Arms Weapons - Weapons that come with the Arms:
- Sword Bringer - One of Idunn Ringo Arms' personal weapons
- Apple Reflecter - One of Idunn Ringo Arms' personal weapons
- Forbidden Ringo Lockseeds
- Allows Idunn to transform into Ringo Arms, equipped with the Sword Bringer and Apple Reflector. This Lockseed possesses Helheim powers that could turn the user into an Inves, and was the first Lockseed that Ryoma Sengoku invented. Its effects are also similar to Yomotsuheguri Lockseed, according to Ryoma. It was given to Touka as part of an experiment to allow passage into Helheim. AFter Ryoma defeats and kills her, he has Yoko Minato give it to Kaito.
- Its code is LS-TABOO. Another Forbidden Ringo Lockseed also appeared in Gaim Gaiden: Kamen Rider Duke, in which it was already damaged and was found by Yoko Minato in Kugai Kudo's apartment before giving it to Ryoma as an evidence. This Lockseed was originally used for experimentation of Lockseeds and the Sengoku Driver.
