Eiki Shiki's Court

As the Yama who judges people after they die, Eiki is impartial to anyone when lecturing them, whenever they are human or youkai. Since she is very preachy and is never mistaken about anything, this makes her hard to approach. Despite her stern attitude and seriousness at her job, Eiki has a teasing side, smiling even when revealing the shortcomings of the people she's lecturing. She's described as being polite and patient when lecturing.

Eiki has blue eyes and green hair that is longer on the right side. She wears a dark blue, sleeveless apothecary robe with gold decorations on top of a black skirt and white shirt with one ribbon on both sleeves. She wears a blue and white hat with a gold emblem in front and a red and white bow on the back; the emblem and bow are balanced equally. She also wears black shoes with a red bow on them, and frilly socks. Furthermore, there seems to be a pattern on her uniform that seems balanced and she carries the Rod of Remorse, described above.

Establishing as clear good and evil (black and white) This is as literally stated. With this power, in order to hand down judgements, the charges that have been established once as clear good and evil cannot, no matter what measures the judged person takes, be overturned. The reason why Yukari Yakumo is not good at dealing with Eiki is probably not just because she dislikes preaching, but also because the Yukari that loves chaos and disorder can be said to dislike things to be established as clear good and evil.

Rod of Remorse Always in Eiki's possession, it can be said to be a rod or a piece of wood. Upon writing the charges on this rod, the weight of the rod changes according to the weight of the sins, and the number of times to beat the sinner is also decided, after which Eiki proceeds to do the beating. This is one of the necessary items for use by Yama for punishment. As explained in Perfect Memento in Strict Sense, she carries this rod with her everywhere.

In the past, each rod was used for one person, and thrown away after its usage was finished. However, for the sake of the environment, it seems that they've been changed to use new material that can be erased and reused.

Cleansed Crystal Mirror This is also an item meant for Yama to perform judgement. When a sinner is reflected in the mirror, it reflects all of the sinner's past deeds, though it is tiring to use. It is a dreadful tool for which privacy is even less than worthless, but perhaps because it does not show up in Eiki's sprite, it has a tendency to be forgotten. It can be said that the mirror of the Yama can change shape as they please, but Eiki's mirror takes the form of a hand mirror.

It can even turn these deeds against the person in question, as shown in Shoot the Bullet when Eiki uses the spell card Judgement "Cleansed Crystal Judgement -Aya Shameimaru-" to pit Aya against herself. The "-Aya Shameimaru-" subscript in the card's name suggests that she can create other versions of this card for use against other characters.
