Description
Kojirō, whose full name is Nezu Kojirō, is a key member of the Elusive Warriors and a trusted retainer of the young lord Hojo Tokiyuki. He belongs to the Nezu clan, a powerful family in Shinano province that serves the Suwa Grand Shrine. His background is marked by complication and tragedy. He was born as an illegitimate child, the result of a forced union between his mother, the sister of the Nezu clan head, and a powerful Hojo retainer. His mother died in childbirth, and his father refused to take responsibility. This left Kojirō as an outcast within his own family. To give him a defined place in the world, his uncle, the clan head Nezu Yoriyasu, tasked him with serving as the shadow and stand-in for the clan's legitimate but sickly heir, who was also named Kojirō. This role, while limiting, gave him purpose, strict training, and a path to becoming a warrior.

In personality, Kojirō is lively, energetic, and brimming with vitality. He presents a cheerful and fearless front, armed with exceptional skill for his age. Despite his youthful and exuberant demeanor, he possesses a sharp and analytical mind. In the heat of battle, he remains remarkably calm, constantly observing his environment and studying his opponents to find openings. Among the eccentric and highly individualistic members of the Elusive Warriors, he is the most grounded, sensible, and level-headed, often acting as the composed core of the group.

His primary motivation is a deep and unwavering loyalty to Tokiyuki Hojo. Having grown up living for the sake of another as a shadow, serving Tokiyuki provides Kojirō with a genuine sense of purpose and belonging. He is driven by a powerful desire to protect his lord, encourage his friends, and help fulfill Tokiyuki's mission to reclaim Kamakura. He channels his skills entirely toward serving his liege and proving his worth not as a replacement, but as a dependable and irreplaceable sword for his chosen master.

Kojirō serves as the Elusive Warriors' primary swordsman and frontline combatant. He is a formidable fighter in direct confrontations, providing the raw martial power that complements Tokiyuki's elusive and evasive tactics. He also acts as a pillar of support for the group, offering encouragement and maintaining stability in chaotic situations.

His relationships are central to his development. His bond with Tokiyuki is his most important. He respects Tokiyuki absolutely as his lord and pays homage to him, but they also share a close, brotherly friendship. Tokiyuki's acceptance of Kojirō for exactly who he is solidifies the young swordsman's identity. Kojirō shares a friendly and competitive rivalry with Ayako, a fellow retainer. They often bicker in daily life, yet on the battlefield, they move and fight in perfect synchronization, trusting each other implicitly. His relationship with his uncle, Nezu Yoriyasu, is complex. Yoriyasu treated him harshly due to the circumstances of his birth, but his decision to train Kojirō as the heir's double was ultimately a way to ensure his survival and give him a future. Kojirō holds no resentment and is deeply grateful for the purpose he was given. The high priest Suwa Yorishige recognized Kojirō's potential and selected him to join Tokiyuki's retinue, setting his path in motion.

Throughout the story, Kojirō undergoes significant development. He begins as a capable but reserved warrior accustomed to living in the background, merely playing a role assigned to him by circumstance. As he fights alongside the Elusive Warriors, he evolves into a confident leader in his own right. He learns to express his own will and solidifies his identity, transforming from a shadow of another into the steadfast right hand of Hojo Tokiyuki.

Kojirō is widely recognized as one of the most talented swordsmen of his generation, possessing skills that match those of a full-grown adult. His fighting ability is highly advanced, but his style is defined by more than just raw talent. He has a remarkable capacity to analyze the battlefield during combat, reading his opponents' techniques and coordinating his actions with his allies to exploit weakness. Coupled with his absolute fearlessness and unshakable composure, this analytical acumen makes him an exceptionally dangerous opponent and a reliable protector for those he has sworn to defend.
