Chisei Kuzuryu is a member of Buraikan, the legendary duo that founded Phantom Live. He is a tall, fair-skinned man with short dirty blonde hair highlighted with lighter streaks and deep purple eyes, possessing a slender yet muscular build. At twenty-eight years old, he stands 178 centimeters tall with AB blood type and a birthday of June 21. His stage name is Yasha, and he wears a dragon-motif pendant necklace, his phantometal accessory, which he activates by kissing. Unlike many other phantom live performers who draw on personal trauma to generate illusions, Chisei has an overwhelmingly high affinity for phantoms and can create powerful illusions without having experienced any significant trauma. This exceptional compatibility, combined with his instinctive and outstanding musical sense, allows him to produce captivating music that fascinates audiences worldwide and elevates the Buraikan name to a global level. His personality is marked by a confident, almost arrogant demeanor; he is known for saying lines such as "Did you think you could catch the legend?" and refers to himself as the most beloved legendary rapper in hip-hop. His hobbies are limited to rap, and his listed weaknesses include unsophisticated tastes and people showing him kindness, suggesting a preference for refined experiences and a discomfort with overt emotional gestures. Chisei's primary motivation appears to be the pursuit of musical excellence and the assertion of his legendary status. As a founder of Phantom Live, he and his partner, Shura, pioneered the entire movement and then mysteriously went underground for about a decade before the events of the main story. In the narrative of Paradox Live The Animation, Chisei serves as a legendary figure who represents the origin and pinnacle of phantom live battles. His key relationship is with his Buraikan partner, Shura, whom he considers a treasure he found; their dynamic is central to his character. While initially presented as an untouchable legend, later developments in the broader Paradox Live project show Chisei taking on a more informal role, such as frequenting a ramen shop and giving Shura a hard time, indicating a subtle shift from distant icon to a more familiar, albeit still eccentric, presence. His most notable ability is his unmatched phantometal synchronization, enabling him to manifest overwhelming illusions that other performers can only achieve through deep suffering. This talent, combined with his musical instinct, makes him a formidable force and a benchmark for all other Phantom Live participants.
