Tena Sorimura, alias Phantom Solitaire, is a career criminal operating in Shinjuku. His nickname originated from Tsubaki Iwanome, manager of the Materials Compiling Group No. 3 police unit. Sorimura's history includes a three-year spree of elaborate crimes designed to attract genuine supernatural entities. These encompassed stealing a museum painting to display at Shinjuku's Studio Alta, camouflaging the Tokyo Metropolitan Government Building to create an optical illusion of its disappearance, orchestrating a "jumbo jet teleport," staging the "Shinjuku Imperial Garden Dream Fireworks," and kidnapping Japan's Prime Minister alongside every opposing party leader in one day. These globally notorious acts ultimately disappointed Sorimura due to receiving no acknowledgment from authentic supernatural beings, leading to his voluntary surrender before the main storyline. Physically, Sorimura sports dark, wavy hair with long bangs, a pencil mustache, and prominent dark circles under his eyes. Incarcerated in a white straitjacket over a prisoner's uniform, he demonstrated the ability to free himself from restraints. Outside prison, he typically dons a business suit with a shoulder cape, styling his hair slicked back to reveal his eyes. He occasionally adopts disguises for covert operations. Sorimura exhibits a theatrical, whimsical, and performative personality. He treats Shinjuku as a stage for audacious crimes aimed at an imagined supernatural audience, viewing ordinary humans as props or secondary spectators. His core motivation is an obsessive quest to prove the existence of magic, ghosts, UFOs, mythological creatures, and occult phenomena. This drives him to embrace high-risk situations at the slightest hint of supernatural activity. He operates spontaneously, improvising plans while employing bluffing, exaggerated confidence, and lies to navigate unexpected developments. His impulsiveness and attraction to danger resemble a moth drawn to flame. Despite his showmanship, he displays considerable intelligence and resourcefulness in executing escapes and complex schemes. A recurring theme in his dialogue celebrates life's wastefulness as enjoyable. His chronology began with the three-year crime spree and imprisonment. After reports of supernatural skeletons during the Shakuzawa Building fire and leveraging information from a visit by Iwanome and Gōzaburō Arase, Sorimura escaped Tokyo Penitentiary by freeing himself during a power outage. Immediately after, he paid ¥30,000,000 to a criminal contact called The Grocer to hijack Tokyo's broadcast signals, announcing his comeback as Phantom Solitaire and giving authorities a one-week notice. Post-escape, he encountered the arsonist Fire-Breathing Bug. Sorimura lured the Bug with a specific ringtone and dueled him, defending himself via magic tricks and athletic maneuvers while probing for genuine supernatural power. He infiltrated a building the Bug set ablaze, retrieving a human-skin-like scroll bearing a strange symbol. Recognizing its supernatural potential, he made it his comeback's centerpiece. This led him back to Tokyo Penitentiary disguised as a security guard to bargain with The Grocer about the symbol. He also visited the Corpse God (in Polka Shinoyama's body) in disguise, learning from the entity that the symbol was drawn incorrectly. His investigation included deploying decoy dirigibles that were shot down, suggesting police corruption. These actions collided him with factions like Xiaoyu Lei, Lemmings, and the Fire-Breathing Bug, culminating in chaotic confrontation. A spin-off, "Phantom Solitaire's Art of Disguising Oneself as a Supernatural Being" (or "Phantom Solitaire's Supernatural Impersonation"), explores Sorimura's past in greater depth. This biographical gaiden novel, adapted into a manga, chronicles his transformation from aspiring magician to Phantom Solitaire, blending prequel elements with main-storyline present scenes. It introduces key backstory figures: Korone Komura, a Weekly Dry reporter who became his exclusive "Solitaire keeper" after witnessing his debut crime, and Emihiko Himura, a veteran reporter referenced in the main manga. New characters Charlot Fistrance and Misa Kuroyashiki appear, while established characters like Tsubaki Iwanome, Kōzaburō Arase, Kochou Eightport, and Gioacchino Soldati feature in younger forms during the three-year flashback. The narrative uses material originally conceived but set aside during the main story's development.
