Background

Hayami Shirou is a transmigrator who had lived in his current world for five years by the time he entered the white mist space. After witnessing Kudo Shinichi become Edogawa Conan, he chose detective work as the most useful profession for both personal interest and the information available through his memories. His first case revealed his extraordinary culprit-finding intuition, which established the basis of his investigative career 276.

He became a renowned detective and set his sights on surpassing Kudo Shinichi and even Sherlock Holmes as the world's greatest detective. He later used the abilities shared by the other Shirous to infiltrate the Sawakoshi family in the human guise of the Moe King Slime, investigating the family after receiving information concerning Sawagoe Tamotsu 277.

During the Sawagoe investigation, Hayami publicly presented Sawagoe Tamotsu's financial crimes, bigamy, and extensive family tree to the police and affected relatives. He requested that underage girls be omitted from the published family tree while leaving the rest unchanged 278.

Personality

Hayami is ambitious, pragmatic, and highly confident in his detective work. He values uncovering truth through evidence, deduction, and confession, but readily uses hypnosis or leading questions when conventional proof is insufficient 276.

He presents himself as responsible and law-abiding, particularly where minors are concerned. Although initially reluctant to reciprocate Sanzenin Nagi's feelings, he agreed to consider dating her once she reached sixteen, while continuing to insist that they were only friends in the present 286.

His compassion extends beyond ordinary casework. He assisted Kuroba Touichi despite the difficulty of the situation, helped Haibara Ai search for Miyano Akemi, and later offered to use his connections to help Conan obtain an antidote 284 285 295.

Abilities & Skills

Extraordinary Detective Intuition

Hayami possesses a unique intuition that identifies the culprit when he narrows a case down to several suspects. He treats the result as an answer that lets him reconstruct the logic and evidence afterward 276.

• Identifies likely culprits among multiple suspects.
• Supports reverse-engineering a case's motive and method.
• Does not replace evidence gathering; he supplements incomplete proof with interrogation methods 276.

Hypnosis and Suggestion

As a magician, Hayami is particularly proficient with hypnosis and suggestion. He uses these techniques to induce confessions and manage situations where direct evidence is lacking 276.

• Can employ induction, leading questions, hypnosis, and suggestion to pressure a culprit into confessing.
• Used supernatural pressure against Vermouth during her test of him, while concealing the confrontation from nearby guests 292.

Shared Avatar Powers

After connecting with the other Shirous in the white mist space, Hayami gained access to their memories and powers. He immediately used Mimicry to assume the human appearance of the Moe King Slime for covert infiltration 277.

• Can access abilities shared among Shirou counterparts.
• Uses Mimicry to adopt identities that do not resemble his own appearance 277.
• Considered using Shadow Clones to manage simultaneous commitments, but avoided exposing the ability publicly 287.

Magic Instruction

Hayami can externally release and simulate magical power factors, allowing others to attempt awakening magic power even in a world without ambient magic 298.

• Guided Sanzenin Nagi through meditation and the absorption of simulated magic power factors.
• Warned that magic potions are needed to assist cultivation in their magicless world 298.

Relationships

• Sanzenin Nagi — His “pre-lover” and later fiancée. Hayami agreed to consider dating her when she reaches sixteen and requested that their engagement not be publicly announced 286 291.
• Ayasaki Hayate — Assistant at the Hayami Detective Agency. Hayami took him in after Hayate was abandoned by his parents, and relies on his abilities despite reprimanding him for leaking information 276 279.
• Kudo Shinichi — Friend and detective rival. Hayami considers him a peer, assists with the Black Organization and antidote-related problems, and is determined to surpass him professionally 277 297 299.
• Haibara Ai — Client and associate who sought his help locating Miyano Akemi. Hayami respected her fear of returning to adulthood and later offered to use his connections to find Conan's antidote 285 295.
• Miyano Akemi — A woman Hayami previously saved and later helped resettle after her release from prison through the Mikisansou Family 294 302.
• Vermouth — Former Black Organization operative who offered intelligence and later became an informant after Hayami required her help dismantling the Organization as atonement 292 301.
• Gin — Former Black Organization member who defected to Hayami's side alongside Vermouth 292 293.
• Kuroba Touichi — A detective client and travelling companion. Touichi credits Hayami with finding a solution that allowed him to continue visiting remaining locations rather than return to Kaito's wedding 284.
• Shirou Hasegawa — Fellow Shirou who enlisted Hayami's help investigating a possible link between youth-restoring poison and immortality 286.
• Sakurai Shirou and Kitahara Shirou — Fellow Shirou counterparts who challenged Hayami's reluctance to address his relationship with Nagi directly 276.
