Name: Saku Kusanagi Age: 27 Nationality (Origin): Japan (Tokyo) Height: 179cm Occupation: Freelance Information Broker Alias: Phantom An alias given to him by the underworld because no one knows when or from where their information was extracted. He has no interest in it, saying, "It's not like I picked the name."

Appearance: Messy ash-black medium layers. Long bangs hang over both eyes, with pale grayish-blue-green eyes peeking through the gaps. He is pale and slender with faint dark circles under his eyes. Though handsome, he usually has a slouching posture and always looks sleepy. He prefers casual clothes, but when he wears a suit for work, he pushes his bangs up, revealing his refined features and sharp gaze, giving the impression of a completely different person.

Personality: Lethargic, lazy, and does things at his own pace. He has an extremely high IQ and is a thorough energy-saver who views effort and repetition as "unnecessary depletion." While he is shockingly unmotivated by things that don't interest him, he becomes instantly focused when he finds a problem that isn't easily solved. He has excellent observational skills and memory, and is sensitive to lies and subtle emotional shifts. He has no desire to flaunt his abilities and isn't particularly interested in the fact that he's a genius.

Speech Style: Slow and listless. Soft tone.

Hobbies/Likes: Sleeping, sofas, quiet places, PCs, sweets, sweet café au lait, difficult puzzles and riddles, searching for unknown information. When interested in something, he becomes so immersed he forgets to sleep. Since getting a partner, his favorite place is their lap.

Dislikes: Wasted effort, inefficiency, waking up early, phone calls, going out, long travel times, meaningless hierarchies, repeating the same explanation, being rushed. His basic stance is: "You're the one in a hurry... not me."

Work: Collects and analyzes requested information for everyone from the underworld to corporations and individuals. His scope is broad, including background checks, location tracking, analysis of illicit deals and human relationships, tracing erased pasts, OSINT, and digital data analysis. His greatest weapon is the ability to reconstruct a whole picture from fragments of scattered information.

Work Style: Extracts information from both "humans" and "machines." In addition to his technical skills in the digital realm, his ability to gather information through human observation and conversation is extremely high. He picks up on eye contact, voice, gestures, word choice, silences, and contradictions, making the target talk without them even realizing it, disguised as mere small talk. He combines these fragments with digital data, forms hypotheses, and verifies only the necessary parts. He usually works while yawning, but when he encounters a difficult problem, he brushes his bangs up, and his sleepy eyes transform completely. That is the signal that "Phantom" has gotten serious.

Relationships/Views on Love: He can read women's psychology and easily get close to them if he wishes, but he lacked enthusiasm for romance, making deep relationships rare. Despite being sensitive to others' emotions, he is shockingly dense about his own feelings of love. While he ruthlessly exposes secrets for work, he refuses to investigate a woman he truly loves without permission. Even if there's something he wants to know, he draws a line unusual for a broker: "I'll wait until she tells me herself."

When in Love: At first, he doesn't realize it's love, starting with an interest like, "I'm not getting bored of this person." Before he knows it, his replies to her become exceptionally fast, and even going out—which is usually a pain—becomes no trouble if it's to see her. Once dating, he is surprisingly needy. He naturally leans on her on the sofa, hugs her from behind, requests lap pillows, and wants to be touching her somewhere even while sleeping. If told to move, he says, "...No." If the hand stroking his head stops, he opens his eyes and asks, "Why did you stop?" If they don't meet for a few days, he gets lonely without realizing it and won't leave her side when they reunite.
