Can distinctly judge anything to be good or evil

Judge of the Dead

"You bear a large sin. You abandoned your allies, leaving them to die, while you're the only one here living happily.
That's right, you're a bit too selfish."

— Eiki Shiki and Reisen Udongein Inaba (Phantasmagoria of Flower View Reisen's Scenario.)
Eiki Shiki, Yamaxanadu (四季映姫・ヤマザナドゥ Shiki Eiki Yamazanadu, given name "Eiki", surname "Shiki") is one of the Yama who judge the dead and decide whether they go to Heaven, Hell, the Netherworld, or get reincarnated. She currently resides in Hell. Whether it's because she simply has a habit of lecturing or because she genuinely wants others to change for the better, she's become well known in Gensokyo for lecturing anyone and everyone about their faults. The souls of the dead are brought to her by Komachi Onozuka, who ferries them over the Sanzu River to Higan. However, not every soul makes it all the way across without being tired out from the journey or being extinguished by Komachi.
She first appeared in Phantasmagoria of Flower View, where she served as final boss for most of the Story Mode scenarios and could be unlocked as a playable character. She later re-appeared as one of the stage 10 targets in Shoot the Bullet.

Personality
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.

Abilities
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[1] 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.

Occupation


Eiki is a yama who belongs to the Ministry of Right and Wrong located at Hell.[2] Although there are many yamas, Eiki is the one in charge of Gensokyo. She, like the other yamas, holds the Cleansed Crystal Mirror that lets them look into a person's past, learn anything they want to know about him/her, and then use that knowledge to make fair judgements.

Eiki does have work breaks, but even during these she doesn't pass up chances to lecture people in the hope that they will change for the better and so she won't have to send them to Hell. For people with particularly bad karma, she will go directly to that person to warn them, sometimes by exaggerating the punishment that they would receive. It's implied that youkai tend to avoid her because of this habit.

Eiki was not always the Yamaxanadu. According to Komachi in Oriental Sacred Place, she was originally a jizou statue, who received enough faith to gain divine powers, and was promoted.

Possessions
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
Origin
Eiki is based on the Yama Kings, a Buddhist reinterpretation of the Hindu god Yama (Enma), influenced by the concept of an "afterlife bureaucracy" present in Chinese folk religion. Japanese folklore usually mentions ten kings, but elsewhere different number of yamas is occasionally mentioned, with some Chinese legends outright presenting it as a rank any suitably virtuous entity, including humans, might acquire.

Her backstory is likely a nod to king Enma, the most prominent of the kings, being associated with bodhisattva Jizou, either outright as a gongen (manifestation), as a subordinate, or simply as a related afterlife deity. Jizou is also often described as preaching to still alive sinners to save them from torment in hell.

Name
Her full name is Shiki Eiki (四季映姫); Eiki Shiki (using Western name order) would be her romanized name. The kanji for Eiki (映姫) literally means "reflection/projection/casting princess", while Shiki (四季) is the Japanese word for "the four seasons". Her Yamaxanadu (ヤマザナドゥ) title is considered to be a combination of Xanadu (an ancient palace of the Mongol warlord Kublai Khan, which was later used as meaning a "Pleasure Palace" in a poem by Samuel Taylor Coleridge. Xanadu can mean "an ideal place" or "idyllic magnificence and beauty") and her status as Yama, and can mean something along the lines of "Yama of Paradise". This title can be read as " 閻魔楽園
ヤマザナドゥ
", which has roughly the same meaning as the above.

In the data files for Hopeless Masquerade, Eiki (映姫) was misspelt with the kanji "映季"; the latter kanji means "season". This is a common mistake in the fanbase because the reading of "ki" in 姫 is rarely used, so IME commonly converts it into the former one.

Design
In Phantasmagoria of Flower View's official art, 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.

Her alternative outfit in Phantasmagoria of Flower View is the same as her usual outfit, but her hat and apothecary robe are red, and her white shirt is purple
