Koishi Komeiji (古明地 こいし Komeiji Koishi) is Satori Komeiji's younger sister. To escape the fear and hatred which other beings feel towards satori, she attempted to destroy her mind-reading ability by closing her Third Eye. However, this had the side effect of sealing away her own conscious mind, causing her to lose all thoughts and motives; she could no longer be hated, but neither could she be loved, or even remembered by people who saw her.

General Information[edit]

Koishi's presence cannot be "felt" by anyone unless she has entered their direct field of vision, and is forgotten as soon as she leaves it. In general, she doesn't have a personality. However, children enjoy her presence as one of an imaginary friend, whom they forget about once they grow up. However, as Satori's presence has been made known, even Koishi has begun to be recognized as of late.


Ability to take action unconsciously

As her actions are controlled entirely by her subconscious, Koishi's presence cannot be noticed by other beings unless she allows it, even while standing in plain view. Likewise her older sister cannot read her mind, as she does not technically have a mind to read. Even someone who manages to communicate with Koishi will forget about her after she leaves, unless they already knew of her as Satori's sister.

Some children are immune to this effect due to their still-developing minds, leading Koishi to become their "imaginary friend", though they will forget about her when they grow up.[1]

Manipulation of the Subconscious

She can manipulate the subconsciousness of every living thing around her, allowing her to make them see everything she desires[2] [3] and make them confront their own weaknesses hidden inside their hearts, as seen in lot of her Spell Cards.


Koishi currently resides at the Palace of the Earth Spirits, but she is also a laywoman in regards to the Myouren Temple as a recent convert to Buddhism, at Byakuren Hijiri's request.


Koishi wanted to receive the blessing of Kanako Yasaka so she could give her own pets power like Satori's pets were given, so Koishi does apparently have pets.

Character Design[edit]


Her surname Komeiji (古明地, lit. "ancient-bright earth") is an actual Japanese surname, seen mainly in the Yamanashi prefecture. There are two common ways to interpret her given name Koishi, based on which kanji are used. The kanji in "恋思", though not a Japanese word as a compound, mean "will/thought of love." The second writing, "小石", means "little rock." This could be connected to her ability, indicating her lack of presence, as she is often compared to a little rock sitting on the side of the road in official texts.


Has wavy, grey-greenish, short hair and dark green eyes, wears a black hat with a yellow ribbon around it. A closed, dark blue "third eye" is positioned over her heart, with cords wrapped around her torso and attached to each of her ankles. Wears an orange shirt with diamond-like blue buttons and dark green collar. The skirt is also green with a faint flowery pattern, but a lot lighter. Her socks are black.


Subterranean Animism

After the events of the main story in Subterranean Animism, Koishi heard that her sister and pets fought a human from above ground, and also heard about Utsuho's new power. Desiring that kind of power for her own pets, she decided to go to Gensokyo to pray for divine blessings. Thanks to her subconscious ability, she managed to reach the Moriya Shrine atop of Youkai Mountain around the same time the Heroine decides to pay a visit to the Gods in the Mountain in the game's Extra Stage. Koishi provokes a fight, and is defeated. After this encounter, however, Koishi somewhat regretted having closed her third eye and became curious enough to want to start actually meeting people.

Symposium of Post-mysticism

While talking about the underground youkai, Byakuren becomes interested in Koishi, as she thinks her state of mind - one of emptiness - is quite close to enlightenment. At the monk's request, Koishi converted to the Buddhist faith.

Hopeless Masquerade

Stumbles across Hata no Kokoro's lost mask of hope and picks it up. This bit of hope added to her otherwise emotionless state allows her to gather popularity when she would otherwise be invisible. She ends up so attached to the mask (subconsciously) that she refuses to return it to Kokoro and ends up keeping it after the conclusion of the story.


Satori Komeiji

Koishi's most important relationship is her older sister, Satori Komeiji. Despite Koishi closing her mind and seemingly whimsical wandering, as well as the fact that even Satori has trouble "seeing" her, Satori does worry about her.

Rin Kaenbyou & Utsuho Reiuji

Koishi is also acquainted with Satori's pets, which include Rin Kaenbyou and Utsuho Reiuji.

Byakuren Hijiri

Byakuren has an optimistic view of Koishi's condition, believing that she is close to enlightenment, invited her to join the Myouren Temple. Koishi accepted, but as a laywoman rather than a priest.[4]


Spell Cards[edit]

Additional Information[edit]

  • Koishi's musical theme, Hartmann's Youkai Girl, may refer to Eduard von Hartmann (whose most famous work is entitled The Philosophy of the Unconscious) or Heinz Hartmann (as many of Koishi's spellcards seem to make references to ego psychology.) The track itself is also arranged so that it has symmetrical parts, making it sound remarkably similar to itself even when played reversed, possibly as a reference to the practice of backmasking.
  • Satori and Koishi's design may have been inspired by the 1939 painting by Kahlo titled "The Two Fridas". The subject is essentially two identical women (sisters/clones/twins...) with visible hearts and external arteries that seem to connect and wrap around their shoulders and arms, where one of them has a cut artery and a pair of scissors in hands (resembling Koishi, who has closed her third eye).
  • Since many aspects of Koishi are references to psychology, there's a running joke that her "Embers of Love" spellcard is a reference to the phallic obsession of Freudian psychology. For those that do not get the hint, look closely at the shape of the bullets. Of course if you think that, maybe Freud was right.
  • Koishi's design can also be referenced to all the bosses in Ibara, as both Koishi and the Rose sisters have white hair and has a lot of reference to roses (although roses in Ibara are point items instead of bullets)
  • If her's and Satori's color schemes are inverted, they will both somewhat resemble each other.
    • One of her colors in Hopeless Masquerade is her sister's color scheme.
  • Some fans believe that her name and her are references to Doraemon's gadgets Ishikoro Boushi (石ころぼうし, lit. "rock hat"), which by wearing, the user's existence faints out making him/her "unnoticeable", very similar to Koishi's ability.
  • The ending of Koishi's storyline in Hopeless Masquerade suggests the origin for the name of Koishi. "Once hope is lost no one will be able to see her (Koishi) again, just like a small rock (小石, pronounced koishi as well) on the roadside."


  • Koishi is occasionally drawn with some sort of connection to Flandre Scarlet, since both are extra-bosses who are the younger sisters of the owner of a mansion from the same game, as well as being explicitly noted as being stronger than their siblings and isolated from them.
  • Koishi in fanon is usually kooky, sometimes overly affectionate kooky (particularly to her sister), just zany, or an utterly unrepentant mind-rapist (most infamously so in the "Koishi Komeiji's Heart-Throbbing Adventure" video series).
  • Some jokes were made about the Hartmann in her theme title being the infamous drill sergeant of Full Metal Jacket fame.
  • Her ability to manipulate the sub-consciousness of those around her (masking herself and thus becoming essentially invisible) have been described as a Somebody Else's Problem Field.
  • Similar to Kahlo's painting mentioned above (The Two Fridas), some fan works display the cord(s) to her third eye being of having already been cut, while Satori's remains intact.
