Riruka Dokugamine

is a member of the mysterious organization, Xcution.

Appearance
Riruka has the appearance of a young girl with long, dark hair that she keeps in two ponytails between which she wears a pale hat. She wears a dark dress and long, dark boots that reach above her knees.

Personality
Confident and somewhat playful, Riruka appears to be an impatient, hot-tempered young girl, that unleashes her wrath even towards her comrades if they disagree with her. She claims to be with her group only for her own agenda and not out of any loyalty to Kūgo. She is extremely talkative and is capable of having ongoing one-sided conversations about irrelevant topics. She suffers from extreme myopia but avoids wearing glasses out of her vanity and claims contact lenses make her large eyes go dry too fast.

The Lost Substitute Shinigami arc
Riruka appears outside the Unagiya Shop along with Kutsuzawa, claiming that they had failed in their goals and that it was Kūgo's fault for not showing them her face. She claims that Kūgo is not her leader but their comrade, stating that he wasn't any good at wooing people which Kutsuzawa contradicts much to Riruka's annoyance. She still claims otherwise but Kūgo asks her to be quiet and not reveal their plans to those who can hear before walking off.

Riruka is later sent to pick up Yasutora Sado, although she is disgruntled about having to do it. When she returns to HQ, Riruka berates Kūgo for summoning his sword. She complains about the lack of light and not being able to see, but Kūgo just tells her to put on her glasses, which she refuses to do. As she cannot see Ichigo she asks who he is but Kūgo insists she come in first. Riruka complains about him bossing her around and tells Sado to go inside.

Riruka is surprised that Ichigo and Sado know each other and asks if she was the only one oblivious to this. Annoyed that Kūgo is ignoring her, she suddenly realizes who Ichigo is and demands that the lights be turned up so she can see his face. Kūgo tells her to wait and continues explaining about Xcution to Ichigo. When Ichigo agrees with their plan to restore his powers and in the process turn them into normal Humans, Riruka objects, wondering if they should trust him so easily. She shines a flashlight on Ichigo to get a better look at him. She is surprised to find that he is rather attractive. When Ichigo returns to the headquarters of Xcution for training, Riruka appears with a box which is related to her power. During that time she argues with Yukio about him seeing her underwear when she opens the door with her foot. She explains to Ichigo that she can transfer him into her box by thinking awesome things about an object. She does so and tells Ichigo to defeat the bear inside.

Fullbring
Fullbring works by allowing her to manipulate the souls that reside in matter. According to Riruka, her powers, known as "Doll House", allow her to transfer anything into an object that she thinks is cute or awesome regardless of the size of either the object or the target she is transferring, so long as she gives it a Pass and permits it to enter. The Pass appears to be shaped like a heart and sticks to the object she wants to transfer over. Her abilties seem to be activated when she speaks the command, "I permit you".
