A yama responsible for judging the souls of the dead, having the ability to identify good and evil. She is best known, however, for being quite moralistic and calling out other characters on their faults - more so (sometimes with physical punishment) upon her errant shinigami, Onozuka Komachi. Based on her illustration from "The Grimoire of Marisa", fanworks often comically depict her as rather petite and flat-chested compared to her imposing, busty employee - something which angers Eiki - though a full-figured woman with long legs and zettai ryouiki is another depiction often used in fanart. Canon is inconsistent on which form is true, with some speculation that the child depiction is used as an alternate form for reasons unknown.
Yamaxanadu (ヤマザナドゥ) is her title (meaning "Yama of Paradise"), but has led fans to erroneously read her name as "Shikieiki Yamaxanadu". In actuality, her given name is Eiki and her surname is Shiki.
