Infamously known as Phantom Solitaire, the dramatic illusionist Tena Sorimura is always searching for the perfect audience to appreciate his lavish performances. However, since stealing priceless paintings and making entire buildings disappear are not exactly legal, he often catches the attention of the authorities. This biographical spinoff manga from Dead Mount Death Play uncovers the origin of this magician turned criminal prankster. The story takes place in modern-day Shinjuku, setting the stage for Sorimura's elaborate schemes that blend stage magic with grand-scale criminal acts.

The narrative follows Tena Sorimura, a showman who treats every heist as a performance and refers to his crimes as entertainment for a select audience. Unlike many antagonists in the main series who possess supernatural abilities, Sorimura operates purely through ingenuity, sleight of hand, and theatrical misdirection, making him a distinctive foil to characters with genuine otherworldly powers. The spinoff intercuts between his early criminal debut and scenes from the main manga's present-day storyline, revealing how he first established his reputation in the Shinjuku underworld.

Several familiar faces from the original series appear alongside Sorimura, including Tsubaki Iwanome, Kozaburo Arase, Kochou Eightport, and Gioacchino Soldati, who find themselves drawn into his elaborate schemes as either pursuers or unwitting participants. New characters also populate this world, such as Korone Komura, a rogue reporter who accidentally got caught up in Sorimura's debut crime three years ago and subsequently became his exclusive keeper, along with Charlot Fistrance, the daughter of the Fistrance Group president who comes to Japan as a bureau chief. Other troublemakers mentioned in the main series finally appear here as well, including the Poisoner, an elderly man who frequents the underworld and wears a gas mask, and Riddle Riddle, a Shinjuku troublemaker who asks unintelligible questions through masks adhered to his face.

The narrative explores how Sorimura pursues rumors of genuine supernatural phenomena within a world that he considers dishonest, using his performances not merely for thrill-seeking but as a method to flush out real magic and extraordinary beings. His encounters with individuals like the Fire-Breathing Bug demonstrate his unique approach, engaging dangerous figures through conversation, card tricks, and psychological games rather than direct confrontation. The spinoff maintains the tone of the original series while offering a more focused character study of one of its most enigmatic figures, blending action, mystery, and the theatrical flair that defines Sorimura's identity as Phantom Solitaire.
