ریریوکا دوکیوگامینای

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.

Riruka is really hyperactive, tsundere and she gets annoyed pretty much by everybody, especially by the Fullbringers. Her tsundere attitude is always seen: for example, she cares about Orihime but always hides it.

[Spoiler: She seems to have romantic feelings for Ichigo, since she almost fainted when she saw him first time, also saying "He's hot!".]
