Kazuichi Banjō rose to prominence as the ghoul leader of Tokyo’s 11th Ward, cultivating unwavering loyalty to Rize Kamishiro. He championed her leadership in ward assemblies and sought to consolidate local factions after her disappearance, convinced she had designated him as her successor. This devotion sparked confrontations with Aogiri Tree when they targeted Rize, leading to his forced recruitment. Tasked with tracking her in the 20th Ward, he crossed paths with Ken Kaneki, misidentifying him as her ally due to their shared scent. Captured together by Aogiri operatives, Banjō orchestrated a collaborative escape, only for Yamori to intercept their efforts. Freed during the 11th Ward Battle, he pledged allegiance to Kaneki, joining his faction. Banjō proved instrumental in critical missions, confronting Gagi and Guge during the Kanou Laboratory raid and shielding his subordinates from Tsukiyama’s vendetta. Though injured in these skirmishes, his rapid regeneration and tenacity ensured swift recoveries. Post-timeskip, Banjō ascended as the 6th Ward’s unifier, harmonizing its fractured groups and honing strategic prowess. Uniquely, he harnessed his ukaku kagune for healing—an anomaly among ghouls—while maintaining a pacifist ethos focused on safeguarding others. In the Third Cochlea Raid, he allied with Ayato Kirishima to extract Hinami Fueguchi, declaring his motives purely personal. He masterminded the infiltration, clashed with CCG squads, and mended Ayato’s wounds mid-retreat using his kagune. His leadership thrived on empathy. He nurtured steadfast bonds with followers Ichimi, Jiro, and Sante, who weathered countless battles at his side. Despite sustaining near-fatal injuries from Kaneki during a psychological rupture, Banjō forgave him, respecting his capacity for compassion. His protective rapport with Hinami mirrored sibling kinship, evident in his affectionate nickname “Hina-chan.” In later endeavors, Banjō contributed to the coalition Goat, applying his expertise in ghoul governance. He aided in healing Akira Mado, mediated friction with Seidou Takizawa, and supported Nico’s proposal to secure treatment via the Great Wheel. His influence broadened to forge alliances across ghoul-human lines, transitioning from a ward-centric figure to a pivotal bridge in interspecies diplomacy.
