Description
Tatsuuma Ushiyama, nicknamed "Ushiyama the Undefeated," hailed from Mikawa province in modern-day Aichi. He trained in judo for ten years, never suffering defeat. An affair with his master's wife culminated in Ushiyama killing his master and brutally injuring ten fellow students who sought vengeance, leaving one permanently disabled. This act sent him to Abashiri Prison.

Ushiyama possessed a massive, muscular frame, towering at 188 cm and standing as the tallest character in the series. Distinctive features included cauliflower ears from judo, a heavy brow ridge, and a thick square bump on his forehead formed by his dense skull. He typically wore a black three-piece suit with a tie and vest. His back and torso displayed the standard Abashiri convict tattoo.

His personality blended hedonism, pragmatism, and dry humor. Ushiyama exhibited relentless sexual desire, prone to violence if deprived of intimacy too long, yet professed deep respect for sex workers, calling them "Kannon bodhisattva." He relished challenging fights and respected formidable opponents, forging an instant bond with Sugimoto due to his strength. Despite ambitions for gold, he offered cautious counsel to allies like Hijikata.

Ushiyama's combat prowess stemmed from expert judo honed by daily practice with a 60 kg rice bag to strengthen his sweeping techniques. His throws could shatter bones and ankles. He demonstrated immense physical strength, capable of hurling adults through ceilings and grappling Kodiak bears. His most noted trait was extreme durability, particularly his impervious skull, which resisted a katana slash from Hijikata.

First encountered in Otaru, he joined Hijikata's group after a violent confrontation. Though focused on gold, he participated in missions like recruiting thief leader Zenjirou Shibukawa, witnessing Hijikata's ruthlessness firsthand. He later questioned Hijikata's broader goal of establishing an independent Ezo.

During the Con Artists arc, Ushiyama rescued Sugimoto and Shiraishi from suffocation in Yubari's mines, subsequently aiding Asirpa. Traveling with Sugimoto's group, he adapted to Ainu customs, hesitantly consuming woodcock brains yet enthusiastically praising Asirpa's cooking. His interactions revealed a capacity for cultural appreciation and emotional resonance, notably moved by an Ainu love poem.

In later events, Ushiyama shielded Asirpa from a grenade blast aboard a train, losing his left arm. As he lay dying, he recalled a conversation with Ienaga about "perfection," concluding that sacrificing his life for another embodied this ideal. His final moments depicted serenity and fulfillment before succumbing.
