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 is extremely short sighted 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 another new recruit for Xcution, 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 invites her recruit in first. The recruit she was sent to pick up is Yasutora Sado, much to Ichigo's surprise.
