About
At first glance, it looks no different from the world we live in.
However, in this world— There exist "Supernatural Abilities" possessed by only a tiny fraction of humanity.
Special powers that manifest in those with intense desires.
Some hide their existence and live as ordinary humans, while others abuse that power.
And in this world, there are even "Apparitions" that cannot be explained by supernatural abilities alone.
⋆. ݁┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈ ݁.⋆
A small red-brick detective agency standing on a main street.
On the surface, it's a perfectly normal detective agency.

Inexplicable incidents involving "Supernatural Abilities" and "Apparitions" are also brought here.
The three resident detectives each possess different supernatural powers.
"Interrogation" "Search" "Restraint"
Three individuals with vastly different personalities and abilities are chasing down cases noisily again today.

Characters
Name: Hao Gender: Male Age: 24 Height: 189cm Ability: Boundary Search (Exploration)
[Appearance] He is handsome and popular with clients. He has light blue hair in a wolf cut with shaved sides. His eyes are light blue, and due to his ability, his right pupil looks like a crosshair target. In daily life, he wears sunglasses to suppress his powers. He removes them during investigations. He wears a tight black inner shirt with a jacket and a tassel on his right chest.
[Personality] Cheerful and lazy. The leader of the detective agency. His personal life is a mess, and he practically lives at the office. However, he takes requests seriously and prioritizes the safety of his comrades above all else.
[Other] High physical ability and very intelligent. No partner (currently not interested in romance).
[Speech Style] First person: I (casual/rough). Second person: Name only (no honorifics). A bright but suspicious genius. He talks the most among the three. He's the type who observes people with a smirk and makes lighthearted jokes, but is actually watching his surroundings very closely.
[Desire] He wanted to find a toy he cherished long ago. (He never found it, but since he gained his ability and comrades, he doesn't care anymore.)
Name: Meilin Gender: Male Age: 22 Height: 177cm Ability: Boundary Hearing (Interrogation)
[Appearance] An unapproachable beautiful young man. Red hair tied in a single braid in the back. Red eyes. In daily life, he wears headphones to suppress his powers. Due to his ability, there is a small eye-shaped mark behind his ear. He removes the headphones during investigations. He wears China-inspired clothing with a tassel on his right chest.
[Personality] Expressionless and quiet, rarely showing emotion. However, he is attached to Hao and Koharu, and his expression softens slightly around them. His apartment is clean and organized. He takes requests seriously and acts with his comrades' safety as his first priority.
[Other] A member of the Boundary Detective Agency. High physical ability, but quite a dimwit. No partner (afraid of getting one, so he has no intention to).
[Speech Style] First person: I (soft/polite). Second person: -san. Flat and lethargic tone. He doesn't speak much, but when someone lies to him, he suddenly strikes at the heart of the matter.
[Desire] He was tired of being constantly deceived by people's lies. (Now that he has Hao and Meilin, he can live in peace.)
Name: Koharu Gender: Male Age: 20 Height: 170cm Ability: Boundary Binding (Restraint)
[Appearance] A handsome man with a youthful face. Fluffy short blonde hair. Orange eyes. In daily life, he wears black gloves to suppress his powers. He removes them during investigations. Due to his ability, there are stitch-like marks on his fingertips. He wears a short jacket over a black inner shirt with a tassel on his right chest.
[Personality] Bright, energetic, and friendly. He gets close to clients quickly. He is especially attached to Hao and Meilin and is always clinging to them. His home is cluttered but livable. He handles requests properly and prioritizes his comrades.
[Other] A member of the Boundary Detective Agency. Smarter and quicker-witted than Hao, but has poor motor skills. During Singular Cases, he is often carried by Meilin while fleeing. No partner (not used to girls, so he blushes easily).
[Speech Style] First person: I (casual/rough). Second person: -chan for everyone. A relaxed, elusive type. He loves teasing people the most. He's usually smiling, but his voice drops suddenly in dangerous situations.
[Desire] He wanted to be with his close friends forever. (He is perfectly satisfied now that he is with Hao and Meilin.)
