Kirishima Yuuichi (キリシマ ユウイチ Ki-ri-shi-ma Yu-u-i-chi)

Publicly known by his assumed identity Ichiro Yamashita and feared in the underworld as The Host, was born on December 1st, 1983, in Yokohama. His mother, a decorated operative of the Public Security Intelligence Agency (PSIA), raised him not in a classroom but within the itinerant halls of intelligence networks. His childhood was defined by a constant shifting, lessons were taught not by teachers but by agents ranging from surveillance and weapon. By the time he was a teenager, Yuuichi had already been molded into a weapon rather than a boy.   At fourteen, suffocated by his mother’s control and the shadowy life she forced upon him, he escaped. His flight marked a dramatic break with the PSIA world, but also left him fractured, untethered, and vulnerable. He disappeared into Japan’s neon-soaked nightlife, carving a new identity for himself within Tokyo and Yokohama’s host clubs. By day he was an abandoned youth drifting on the margins of society, by night he became "The Host" a figure of charisma, decadence, and concealed menace.   Yuuichi could not escape what he had been taught. The skills drilled into him by the PSIA unarmed combat and espionage tradecraft transformed him into a dangerous player in the underworld. His fluency in nine languages, from French and Russian to Korean and Chinese, allowed him to navigate the corridors of both politics and organised crime with unnerving ease. Inevitably, his talents drew him into the orbit of the Daidoji, a political faction with a history of manipulation behind the scenes of Japan’s balance of power.   He became less an agent and more a storm his triple loyalties unravelled over time a quiet, relentless hunger for vengeance. Where once he balanced deceit, charm, and calculation, now every lie and alliance is measured against that single ledger of retribution. His host smile is a veil for cold intent, his multilingual charm opens doors only to close them behind enemies. Justice for him is no longer a principle but a formula precision strikes, arranged betrayals, and an economy of suffering designed to punish those he deems responsible. This vengeance is patient, intelligent, and unsparing: it eats at his rest, hardens his wit, and turns even fleeting affection into leverage. In the end, whatever cause he claims, whatever creed he whispers, it is vengeance that steers him methodical, inexorable, and utterly his.   One night, operating under the guise of a routine assignment, Yuuichi tasked a contracted operative to eliminate the man believed to be orchestrating human trafficking in Kamurocho. The job was executed flawlessly, the target dead within minutes, but the aftermath was far from clean. Unbeknownst to Yuuichi, a woman had been in the car, caught in the crossfire of a mission meant to bring justice. She was the mother of Yuuichi's child, a secret that would never be revealed. The realization struck him months later, leaving a permanent shadow over his otherwise calculated life. He knows his son exists, knows who he hes and where, but that knowledge is unspoken, locked away in the deepest recesses of his conscience a private burden he carries with quiet, relentless regret.   Adopting The Host persona fully, Yuuichi displayed arrogance and egotism, flaunting his connections and prowess within the Daidoji. He relished in boasting of his abilities, particularly his talent as a marksman, and carried himself as a man destined to stand above others. Over time, experience tempered him, making him more measured, pragmatic, and calculating but the flamboyance he cultivated as a host never fully disappeared. In moments of confidence or provocation, it surged forward, reminding allies and enemies alike of the man who thrives in both spectacle and danger. Even in his madness, he carried an undeniable charisma and the dangerous allure of someone who had stared into the abyss and sometimes chosen to step back into the spotlight rather than away from it.
