Background / History

Shiraishi was reincarnated into the world with incomplete memories of a previous life. Raised in an orphanage in Kamurocho, he spent his childhood training his body and initially considered joining the Tojo Clan before deciding it had no future. 206 244

At eighteen, he realized he was in Beika Town and abandoned martial arts as his sole focus in favor of academics. Using his Point Allocation System to accelerate his progress, he earned dual bachelor’s degrees in Psychology and Health Science, followed by dual master’s degrees in Law and Forensic Medicine at the University of Tokyo. 2

He passed the Professional Group assessment at twenty-four. Within ten months, his field performance, deterrent presence, and investigative results earned him a place in the newly established Organized Crime Countermeasures Department. After two years leading Unit 4 on the front lines, he became its Section Chief while retaining the rank of Inspector. 2

By the time he arrives at Beika Police Station, Shiraishi has become its Chief Superintendent. He learns that the position depends less on individual ability than management, then begins reorganizing training, personnel use, and casework practices. 16 20

Appearance

Shiraishi is an exceptionally large and heavily built man whose presence is routinely mistaken for that of a dangerous fighter or even a bear at a distance. His physique is intimidating enough to unsettle police officers, detectives, civilians, and yakuza before he speaks. 1 257

• Height: 226 cm 1
• Weight: 159 kg 1
• His build is sturdier than Kyogoku Makoto’s and too large for an economy-class airplane seat or cabin clearance. 1
• His muscular development was intensified by repeatedly investing points into Physique during adolescence. 2
• Under strain, his body can generate intense heat through deliberate trembling and adrenaline control. 152
• When resisting Rasputin’s possession, bloody tears from both eyes give him an especially fierce appearance. 571

Personality

Shiraishi is direct, confident, and highly practical. He values results, evidence, and the development of capable officers over deference to convention or outside detectives. His willingness to personally enter dangerous scenes, confront violent organizations, and accept responsibility for wrongful arrests makes him both respected and politically troublesome. 181 257 336

Despite his aggressive reputation, he is a committed instructor and manager. He holds back while training officers, teaches correct use of riot-control equipment, monitors subordinates’ weaknesses, and assigns work according to their potential rather than merely their current performance. 18 20 46

He is also notably cautious around manipulation, institutional corruption, and supernatural threats. Shiraishi distrusts convenient explanations, scrutinizes mental-health evaluations for conflicts of interest, and maintains independence even when cooperating with Public Security. 261 564 667

Abilities & Skills

Point Allocation System

Shiraishi possesses a system that allows him to spend points improving attributes and skills. It also lets him assess the abilities, potential, personality traits, and unusual conditions of many police officers. 3 20 46

• Invests points in physical attributes, combat techniques, investigative skills, and work-related abilities. 6 38 168
• Identifies personnel suited to specialized work, such as Kanzaki Ryuichi’s potential for forensic science. 46
• Can recognize special abilities and sealed or suppressed skills in others. 20 54

Physical Combat

Shiraishi’s strength, durability, reach, and endurance far exceed ordinary human standards. He can defeat groups of armed opponents while moderating his force enough to avoid lethal injury when necessary. 6 7 18 182

• Defeated most of more than thirty Ryugenkai yakuza in a garage ambush despite gunfire and severe injuries. 6 8
• Trained Beika officers by challenging them to fight him in groups, while instructing them in grappling and riot-control tactics. 18 20

• Can perform one-against-a-hundred battles against armed opponents when equipped appropriately. 695
• His enormous mass and muscle cushioning allow him to endure punishment that would incapacitate other Lv10 fighters. 7

Intimidation and Interrogation

Shiraishi’s Intimidation is Lv7, amplified by Lv10 Spirit to an effective Lv7(+2). Unless opponents possess exceptional willpower or overwhelming numbers, his presence can impair their judgment and composure. 3

• Uses his reputation and knowledge of yakuza customs to compel cooperation from groups such as the Nichikyo-kai and Matsugane-gumi. 336 338
• Recognizes organized-crime affiliation through demeanor, tattoos, hierarchy, and behavioral intuition. 337
• Uses direct pressure rather than prolonged formalities when questioning evasive suspects. 53 336
• Can blend his mannerisms into criminal environments so naturally that accompanying detectives view Kamurocho as his “home turf.” 336 415

Investigation and Forensics

Shiraishi combines advanced evidence handling, deduction, forensic training, and practical field experience. His expertise extends from crime-scene reconstruction to autopsy assistance. 3 38 138

• Evidence Collection Lv7 enables him to quickly identify inconsistencies such as bloodstain placement, wet clothing linings, and scratch marks near wounds. 3
• Upgraded Evidence Collection and Deduction allow him to mentally reconstruct crime scenes and observe reenacted events. 38
• Holds a forensic pathologist license and can assist with autopsies when urgency requires it. 138
• Uses forensic observation to determine cause of death, time of death, and likely primary crime scenes. 607
• Regularly detects missing evidence, false alibis, and motive patterns before his team reaches the same conclusion. 299 702

My Own Style Combat Arts

Unlocked upon reaching Physique Lv11, this combat skill lets Shiraishi exceed normal physical limits and recover rapidly from injury. 8

• Raises his fighting ability beyond the level expected from ordinary human skill alone. 8
• Allows him to continue fighting after gunshot wounds, exhaustion, and heavy physical trauma. 8
• Is strengthened further by his body control and later application of supernatural abilities. 152 571

Supernatural Resistance and Magic

Shiraishi is connected to Crimson Witch magic and can use supernatural power in combat. His physical “Evolution” is less versatile than magic but has fewer restrictions in direct conflict. 571 568

• God’s Left Hand destroys supernatural entities on contact, dispersing dark-magic-corrupted souls and similar manifestations. 571
• Resisted Rasputin’s attempted possession, suffering only eye injuries and bloody tears. 571
• Withstood a curse that would have seriously endangered Ayari, suffering only a rib-muscle spasm. 571
• Can detect anomalies in supernatural practitioners through observation and Ayari’s guidance. 564 568

Second Gear

Second Gear is a temporary transformation developed inside Noah’s Ark. Shiraishi compresses his adult body’s energy into an eight-year-old form, causing visible steam and reddened skin. 604

• Temporarily reaches perfected Lv11 strength. 604
• Developed specifically to fight opponents approaching or exceeding ordinary Lv11 capability. 604
• Its shrinking effect leads Sherlock Holmes to suspect a connection to APTX4869 and Karasuma Renya. 610

Marksmanship and Reflexes

Shiraishi is an unusually capable shooter and responder for a frontline detective. 520 688

• Stops Uno Kensuke’s suicide attempt with a shot and arranges his arrest. 520
• Catches an incoming arrow and throws it back, leading investigators to initially mistake it for a fired projectile. 688
• Can react to gunfire quickly enough to use vehicles, terrain, and his body as protection. 8 571

Equipment / Weapons / Items

• Iron Fist gloves — Worn in the Noah’s Ark Colosseum World, allowing free joint movement while protecting his hands. 604
• Divine Guan Dao — A heavy weapon acquired during the Genji Fire incident; used against sword-wielding opponents. 695

• Megure Juzo — Veteran colleague and mutual-respect partner from the First Investigation Division; they cooperate even when departmental interests conflict. 1 337
• Takagi Wataru — Initially intimidated by Shiraishi’s appearance and reputation, but later accompanies him on organized-crime investigations and learns from his methods. 1 336
• Gen Seiji — Subordinate whose unusual abilities Shiraishi monitors closely, particularly the ethical risks of Absolute Empathy during interrogation. 16 261

• Furuya Rei / Amuro Toru — Public Security counterpart. They cooperate against the Crow Corps while maintaining mutual caution and separate agendas. 667

Story Role / Major Arcs

Organized Crime Countermeasures

Shiraishi first appears while investigating a murder aboard a flight to the United States. His evidence work quickly establishes him as a highly capable Organized Crime Countermeasures detective, while his size immediately unnerves Takagi. 1 3

The Ryugenkai Clan later lures him into a garage ambush. Outnumbered, shot, and pushed beyond his usual limits, he activates the Lv11 Physique trial and defeats the attacking yakuza group. His actions expose the Justice Minister’s collusion with violent organizations, forcing Inukai Ichiro’s resignation. 6 7 8

Chief Superintendent of Beika

As Beika’s Chief Superintendent, Shiraishi reforms the station through intensive training, personnel assessment, and direct leadership. He runs thirty kilometers each morning through all seventeen local kobans, then forces even off-duty officers to attend arrest-technique training. 16 18

He treats Beika’s murder rate and cold-case backlog as management problems as much as investigative ones, directing personnel toward cases according to urgency and available resources. 279

Black Organization and Public Security

Shiraishi repeatedly investigates threats connected to the Black Organization, including bomb plots, assassins, compromised officials, and members operating inside police structures. 263 303 477

He captures Black Organization outer member Kojiro Hishida while the man attempts to destroy evidence, but Public Security later takes custody before Shiraishi can question him further. 477 168

His growing influence leads to tense dealings with Public Security, including Furuya Rei, over the Crow Corps and the aftermath of the ship “terrorist” incident. 667

Egg of Memories and Rasputin

While protecting the Egg of Memories aboard the Suzuki cruise ship, Shiraishi identifies Ura Shiran as suspicious and determines that her alleged Chinese identity is false. He correctly recognizes a Mongolian phrase and links her to Rasputin and the assassin Scorpion. 563 564 568

When Ura takes Kousaka Natsumi hostage and escapes with the Egg, Shiraishi pursues her. He discovers that Rasputin’s surviving soul is possessing Ura, then defeats Rasputin’s corrupted spirit minions and prevents him from taking Shiraishi’s body. 570 571

Noah’s Ark

Inside Noah’s Ark, Shiraishi becomes the Colosseum World’s “Iron Fist,” winning match after match against increasingly inhuman opponents. He develops Second Gear to confront the Demon King in his hundredth battle. 604

In the game’s London setting, he works alongside Sherlock Holmes on a Jack the Ripper case and captures Aaron Sidora after stopping a departing train. Holmes subsequently links Shiraishi’s shrinking ability to Moriarty and Karasuma Renya. 607 610
