Taipei serves Takeru Shinoyama within the Dragon King's Palace Agency as a member of the Heilei criminal organization, performing duties alongside Bao that include acting as Takeru's bodyguard and executing assigned tasks. He possesses a tall, stocky build and consistently wears a wide-sleeved coat over a tang suit. His appearance features a headband beneath a tassel loop, eyeshadow or dark bags under his eyes, and black-painted fingernails, adhering to Heilei traditions. While guarding Takeru, Taipei presents a silent, imposing, and imperturbable professional front, fully committed to his duties. This demeanor conceals a proclivity for violence and a deep-seated sense of superiority. He exhibits cockiness regarding his station and skills, evident in his past behavior toward fellow Heilei member Xiaoyu Lei. Taipei holds societal disdain for outsiders, whom he dismisses as "lowly rabble," and operates based on a belief in hierarchical power structures where strength and connections dictate survival. Taipei operates within the Shinjuku underworld on operations tied to the Shinoyama family. He witnessed Gorō Shinoyama's interrogation after the Shinoyama mansion fire. Confronting Xiaoyu Lei during a police search of Polka Shinoyama's building, Taipei belittled Xiaoyu's value to both the Heilei and Shinoyamas, prompting Misaki Sakimiya to intervene on Polka's behalf. He later reported to Takeru on Xiaoyu's injured condition and missing prosthetic limb, also noting the draining of his bank account by Bao, who redirected the funds to Xiaoyu as an expression of possessiveness. In another operation, Taipei posed as a client for reporter Kochou Eightport to gather intelligence on Polka Shinoyama. He immediately attacked Soara Habaki upon encountering her, correctly identifying her as an assailant by scent. The confrontation resulted in Civil A. Sabaramond's escape, documented by Taipei's surveillance partner. Acting on Takeru's orders, Taipei subsequently requested Polka perform a fortune-telling reading to identify Civil, Soara, and Lulu. Taipei's relationship with Xiaoyu Lei is defined by condescension, reflecting their shared history within the Heilei. Xiaoyu, son of the Heilei's former paterfamilias, suffered severe injuries on his first mission leading to his sale to the Shinoyamas. Taipei's dismissive attitude underscores the Heilei's emphasis on strength and utility. His loyalty remains firmly aligned with Takeru Shinoyama and the objectives of the Dragon King's Palace Agency.
