Bleach introduced Riruka Dokugamine as a deceptively innocent-looking Fullbringer whose rabbit-eared hat and playful demeanor mask terrifying abilities. Member No. 003 of Xcution carries the power to compress entire dimensions into toy boxes, trap seasoned Soul Reapers inside stuffed animals, and infiltrate human bodies undetected. Her magenta pigtails and childlike aesthetic create a disturbing contrast with her capacity to psychologically torment enemies.
In Bleach, Riruka’s combat skills peak with her Dollhouse Fullbring, an ability that transforms everyday objects into deadly weapons or confinement tools, completely altering the flow of battle. She successfully trapped Rukia Kuchiki inside a plushie rabbit and compressed the Valley of Screams dimension for tactical transport. After absorbing Ichigo's stolen power, her enhanced abilities, including Addiction Shot and Human Container, elevated her to a strategic nightmare.
She awakened her supernatural gift in Bleach at the astonishingly young age of five. By six years old, she claimed to be unmatched among her peers. Her childhood was marked by tragedy when she fell in love with an older boy at age seven. Using her newfound powers, she trapped him inside a chest, bringing him treats daily while believing he would eventually return her affections.

This traumatic experience shaped her philosophy about power and survival. The boy's fear became evident in his eyes, ultimately forcing Riruka to release him. This incident taught her that supernatural abilities don't guarantee acceptance in society. Instead, she developed her "survival of the fittest" philosophy, believing that numerical majority, not individual strength, determines who rules in Bleach's complex world.
Riruka later met Shūkurō Tsukishima and Kūgo Ginjō, uniting with other Fullbringers such as Yukio, Jackie, and Giriko to form the group Xcution. The group made a pact to share their powers and support each other's goals. However, seventeen months after Aizen's defeat, they fell under Tsukishima's influence as part of an elaborate scheme to steal Ichigo Kurosaki's Fullbring abilities.
Core Fullbring: Dollhouse in Bleach

Riruka's primary ability, Dollhouse, represents one of the most versatile powers showcased in Bleach. This Fullbring allows her to freely transfer people and objects into anything she finds attractive or adorable. She refers to this as an ability rooted in "love," enabling her to maximize the potential of whatever captures her affection.
The mechanics involve generating small, heart-shaped passes marked with the letter "R." She launches these at targets before using the command "I permit you" to complete the transfer. Her ability forces targets to shrink and fit the exact size of their new container. A simple sneeze from Riruka deactivates the effect, returning everything to normal size.
The practical applications prove incredibly diverse. During Ichigo's training, she placed him inside an actual dollhouse for combat practice. She also compressed a yakuza member into a stuffed pig, demonstrating her ability to layer multiple transfers simultaneously. Most notably, she once condensed the entire Valley of Screams dimension into a small portable box.
Enhanced Abilities After Power Absorption

After Ginjō stole Ichigo’s Fullbring, Riruka gained a massive boost in power that altered both her look and her abilities. Her enhanced form in Bleach features white armor bands on her forearms with yellow spikes, rabbit-ear modifications to her hat, and heart-shaped chest armor. This enhancement granted her several destructive techniques that drastically increased her combat threat.
Addiction Shot became her signature enhanced ability. By pointing at targets and activating the technique, she launches hearts that attach to opponents before transferring them into objects of her choosing. Unlike the original Dollhouse, this evolved version functions at long range with faster speed and greater precision.
The Human Container technique represents perhaps her most insidious ability. Riruka can physically enter another person's body, gaining limited control over their movements while accessing their thoughts and memories. The host remains conscious but helpless as she manipulates them from within.
Riruka's Love Gun serves as her primary combat tool, originally created by Tsukishima before falling into her possession. Her upgraded device resembles a heart with wing-like extensions and a vial of fluid that boosts its energy output. She can load miniaturized objects into the weapon and release them at full size.
All in all, Riruka Dokugamine represents a fascinating example of Bleach's creative approach to supernatural abilities. Her Dollhouse Fullbring, while initially seeming simple, reveals incredible depth and versatility through creative applications. This blend of strength and personality cements her as one of the most unforgettable Fullbringers in the series.
