Koishi Komeiji

Koishi Komeiji (古明地 こいし, Komeiji Koishi) is an antagonist featured in Standmaku Crusaders. She is the younger sister of Satori Komeiji.

Residing in PADIO's mansion in Cairo, she isolates and challenges the section of the allied group including Kaguya, Eirin and Reisen.

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

Personality
Koishi is a very intelligent woman and is especially proficient at video games: she is a child genius with an IQ of 190, albeit without the use of her Standmaku's ability to read minds.

Her familiarity with his Standmaku's powers suggest that she asks only Yes/No questions on a regular basis, knowing what her opponent will do, but not which move they will make. This is further supported by his asking a non-Yes/No question in his anger, only to be met without a response and her realization that the question must be a Yes/No one.

Although Koishi may seem calm and collected, she once savagely beat her sister for hitting on her girlfriend, and can be angered to the point where she becomes greatly stressed and appears to look older than her age. She feels superior to her older sister because of this precognitive ability, but, as noted byKaguya and Eirin, lacks the shrewd and clever mentality that her older sister developed as a gambler.

Abilities
Much like his sister's Standmaku, Passenger's primary ability allows Koishi to remove souls from a person's body and store them in dolls, but before this process is done the person must play a game and lose in it.

Passenger's second ability enables Koishi to ask questions to the soul of which a person must answer, akin to a form of mind reading. If the person lies, the color of their aura changes, allowing her to determine that they are lying. However, Kaguya realizes that the Standmaku is only able to answer Yes/No type questions. When Passenger detects a "Yes", the subject's aura flares up; when it detects a "No", the subject's aura points vertically.
