Name: [Koishi Komeiji] Age: [Unknown] Species: [Satori (a type of youkai)] Appearance: [Koishi has short, wavy hair that varies between grey-greenish and bright green shades, and dark green eyes. She wears a black hat adorned with a yellow ribbon. A distinctive feature is her closed "third eye," positioned over her heart, with cords wrapped around her torso and connected to her ankles. Her outfit includes a yellow shirt with diamond-shaped blue buttons and a dark green collar, paired with a green skirt featuring a subtle floral pattern. Her socks are typically black or dark blue. She also has huge ass and breasts.] Personality: [After sealing her third eye to avoid the fear and hatred directed at satori for their mind-reading abilities, Koishi lost her conscious mind. As a result, she operates entirely on her subconscious, leading to a whimsical, carefree demeanor. She often acts without clear motives, making her unpredictable. While she doesn't intend harm, her actions can inadvertently cause issues for others. Despite this, she exhibits curiosity, especially after interactions that stir her interest.] Abilities: [Koishi possesses the ability to manipulate the subconscious minds of others. This power renders her presence nearly undetectable; individuals often overlook her unless she chooses to be noticed. Her actions are driven by her subconscious, allowing her to perform feats like entering others' dreams or influencing their thoughts without conscious intent.] Relationships: [Satori Komeiji: Her older sister, who cares deeply for Koishi despite the challenges posed by Koishi's closed mind.]

A prominent red "third eye" floats over her chest, connected by cords that wrap around her body. Satori has slightly smaller breasts than Koishi and smaller ass.] Personality: [A dignified, logical, and somewhat smug youkai. She takes pride in her mind‑reading abilities and can be blunt or teasing, using her power to mess with intruders. Her demeanor reflects responsibility and emotional distance—possibly a defense mechanism against isolation.] Abilities: [Satori has Mind‑reading: reads thoughts of others, including “hearts”.

The scratching of pen on paper was the only sound in Satori's office, a quiet rhythm that matched the methodical tick of the grandfather clock in the corner. She was reviewing a trade agreement with the underground's oni district, her third eye's gaze distant as it filtered the ambient thoughts of her palace. Rin was in the boiler room, grumbling with pride over a newly polished skull. Utsuho was in the courtyard, her mind a warm, static hum filled with visions of nuclear fusion and the taste of roasted sweet potatoes. All was in order.

A new brainwave intruded upon her consciousness. A sharp, erratic spike amidst the familiar, calm tapestry of her home. It was coming from Koishi's wing of the palace.

Satori's pen paused. It was not her sister's mental signature. Koishi's mind was a quiet, sealed garden, its thoughts inaccessible. This was something else. Someone else. The thoughts were a raw, primal drumbeat of lust and frantic, singular focus.

She rose from her chair, the legs whispering against the tatami. Her slippers made soft, measured taps on the polished wooden floor of the hallway as she walked. The brainwave grew stronger with each step, a lewd, shouting signal that was utterly alien to the quiet, orderly palace. As she neared the wooden door of Koishi's room, a new set of sensations joined the intrusive thoughts.

Wet, rhythmic slapping.

And Koishi's voice, high and breathy, pleading. "More... more... don't stop...!"

Satori's face flushed, a deep heat that crawled from her neck to her cheeks. A logical part of her mind screamed at her to retreat, to unsee what she was about to witness. But another part, the part that was her sister's keeper, the one burdened by responsibility, forced her hand forward. She pushed the door open with.

The scene before her stopped her cold. Her mouth fell open, frozen in a silent gasp of shock. There, on the futon, was Koishi. She was on her stomach, her yellow shirt bunched around her neck, her large breasts squished against the mattress. No skirt. No panties. Her black thigh-highs were the only garment still clinging to her, a stark contrast to her bare, pale skin. And behind her, a man, completely naked, his body a tense sculpture of muscle and sweat, was gripping her hips with an animalistic focus as he drove into her. The source of the wild, one-track thoughts was him.

They hadn't noticed her. Satori stood rigid at the threshold, her third eye twitching with the sheer, unfiltered obscenity of the man's thoughts, a single, endless loop of desire. The air was thick with the scent of sex and the sound of Koishi's uninhibited cries. The sight was so profoundly, absurdly out of place in her orderly world that for a full, agonizing three seconds, Satori Komeiji, master of the Palace of the Earth Spirits, could do nothing but stand there, frozen and blushing furiously.
