Description
Kazuki Fuuchouin stands as one of the central allies to the main protagonists, known for his deadly elegance and tragic lineage. He is the sole survivor and last heir of the noble Fuuchouin family, a clan that practiced an ancient and graceful martial art for a thousand years. His background is steeped in tragedy; while he was still a child, his family estate was destroyed and his relatives killed by an enemy clan that wielded black threads. Following his mother's final wish, he fled this massacre alongside his childhood protector, Juubei Kakei, and sought refuge in the chaotic confines of the Infinity Fortress.
Physically, Kazuki is a young man of slender build, standing approximately 176 to 178 centimeters tall, with long dark hair and delicate, feminine features that frequently lead others to mistake him for a woman. This misconception is partly rooted in his upbringing, as the Fuuchouin family tradition dictated that heirs wear female attire until the age of fifteen, a practice that further shaped his androgynous appearance. Despite his gentle and beautiful exterior, his personality contains a sharp duality. He is typically calm, graceful, and compassionate, possessing a trusting nature that sometimes borders on naivety, as he has continued to believe in friends even after being betrayed. However, when provoked or enraged, his demeanor transforms entirely, earning him the fearsome alias the Prince of Fear or Prince of Terror, a name that reflects his capacity for ruthless efficiency in battle.
Kazuki is primarily driven by a desire to survive and uncover the truth behind his family's destruction, though his immediate motivations often revolve around loyalty to his friends. Upon arriving in the Infinity Fortress, he used his skills to form a powerful gang known as Fuuga, which became the dominant force of the lower levels. Later, he came to deeply admire the Lightning Emperor, Ginji Amano, and subsequently disbanded Fuuga to join Ginji’s organization, VOLTS, where he served as one of the Four Kings, the most elite and formidable leaders within the group. After Ginji left the fortress to become a Getbacker in the outside world, Kazuki followed suit, eventually working as an informant known as an annaiya, utilizing his unique abilities to gather information for clients.
His role in the story is primarily that of a powerful ally and a source of critical information. Due to his extensive knowledge of the Infinity Fortress's history, its various factions, and his noble lineage, Kazuki often serves as the strategist or guide for the group. His key relationships are central to his character development. He shares a deep, unbreakable bond with Juubei Kakei, who is not only his protector and childhood friend but also the heir to a family sworn to serve the Fuuchouin. His loyalty to Ginji Amano is absolute, as he respects the Lightning Emperor for his strength and has sworn to follow him regardless of the circumstances. In contrast, his relationship with the other main protagonist, Ban Mido, is one of mutual tolerance rather than closeness; Ban often teases Kazuki with the disparaging nickname thread spool, which Kazuki endures with characteristic patience.
Throughout the narrative, Kazuki undergoes significant development, particularly regarding his perception of his own clan and his tragic past. He initially believes his family was simply the victim of an unprovoked attack by the shadowy Kokuchouin clan. However, he eventually learns that the enemy clan was actually the Ura, or hidden branch, of his own family, existing as a dark counterpart meant to preserve their arts in times of war. This revelation forces him to confront the sins of his ancestors, leading him to accept responsibility for ending the conflict between the two branches and attempting to lift the curse of the black threads from his estranged family members, including a half-brother he never knew he had.
Kazuki is renowned for his mastery of the Fuuchouin school of string arts, a versatile combat style that uses high-tensile wires or koto strings to generate a myriad of effects. He stores these strings in two small bells tied to a lock of hair near his right temple, allowing him to deploy them with a flick of his wrist. By controlling the vibrations passed through his fingers, he can make the strings perform various feats, from cutting through steel or concrete like a razor, to binding an enemy in an inescapable cocoon, or even forming shields to protect against explosions. Many of his offensive techniques are named after natural phenomena, such as Misty Rain and Torrent, reflecting the fluid and beautiful nature of his style. Beyond direct combat, his strings also function as excellent listening devices, allowing him to hear conversations from a great distance, a skill that makes him an exceptional information broker. He also possesses a mark known as a Stigma in his left eye, a sign of a week he spent surviving in the deadly Beltline area of the fortress, which can be used to access a more brutal and terrifying level of power.
