As a Queen, Riruka possesses all the powers of a knight, rook, and bishop thus giving her enhanced speed, strength, defense, and magical power.
Dollhouse: Riruka's unique magic gives her the ability to freely move people and objects into or out of anything that she adores or finds cute. Riruka refers to this as an ability of "love," which allows her to draw out the maximum power of anything she falls in love with. To achieve this, she generates a small, heart-shaped "pass" in her hand, which has the letter "R" on it, and then launches it at her target. Once the pass has been attached, she can transfer the target into an object with the command, "I permit you" ("あんたを許可する"わ, "anta wo kyokasuru" wa). The target is shrunk down to accommodate for the size of the object she is transferring it into. She deactivates her ability by sneezing on the object, returning the ones she placed into it to normal. Additionally, if the container affected by Dollhouse is destroyed, its contents are forcibly ejected and returned to its normal size.
Addiction Shot (アディクション・ショット, Adikushon Shotto): Using the command "Addiction Shot", Riruka points her arm at a target and the letter "R" appears in a circular protrusion on the back of her gauntlet. She launches a heart from her fist, which attaches itself to the target. Riruka then calls the name of the target and states that she admits them, allowing her to place the person inside an object of her choosing, such as shrinking someone and placing them inside a plushie. By sneezing on the plush, this effect can be negated, and the sealed person is freed and returns to their original size.
Human Container: Riruka stabs a target with her gauntlets, and the "R" on her gauntlets glow, as light pours from where she stabbed the target. Then Riruka secretly hides herself inside the target. While the host still has control of their body and mind, Riruka has limited control of him or her as long as she is inside the target. When Riruka wants to leave the host, a sideways H with several dots appears on their chest and opens, propelling Riruka out. Additionally, while being inside the person, her presence can't be sensed[43] and she has access to the person's thoughts. Whenever she enters or leaves the target, they fall unconscious as a result.
