Description
Tsuboi Ryoutarou, better known by his avatar Klein, is a stalwart player trapped in the deadly virtual realm of Sword Art Online, recurring across its many arcs. Leading the guild Fuurinkazan, he spearheaded the crusade to clear Aincrad alongside Kirito, championing teamwork and safeguarding comrades. His rugged avatar sports a crimson bandana, spiky reddish hair, and samurai-styled armor, accentuated by a hooked nose and scruffy beard that lend him a roguish, bandit-like demeanor.
During the Aincrad Arc, Klein first crossed paths with Kirito on the game’s launch day, mastering combat basics just before the death game commenced. Choosing loyalty to his friends over solo ventures, he rallied Fuurinkazan through pivotal clashes—from the Christmas Eve assault on Nicholas the Renegade to the GeoCrawler onslaught on Floor 56 and the purge of Laughing Coffin. In the climactic Floor 75 battle against The Skull Reaper, he was immobilized alongside allies after Heathcliff’s shocking reveal as Kayaba Akihiko, later reconciling with Kirito post-liberation.
In later arcs, Klein embraced Alfheim Online as a fire-wielding Salamander, aiding Kirito’s crew in quests like the Deep Sea Plunderers and securing the legendary Excalibur during the Calibur campaign. While spectating the Bullet of Bullets tournament, he unmasked Death Gun’s ties to Laughing Coffin. During Mother’s Rosario, he shielded Asuna and the Sleeping Knights by diverting rival guilds during their boss raids, later joining both celebratory feasts and Yuuki’s solemn memorial.
When Project Alicization beckoned, Klein sacrificed his veteran Alfheim avatar and treasured inventory to dive into the Underworld, battling foreign invaders despite scant records of his exact exploits. This selfless leap underscored his enduring allegiance to Kirito and dedication to collective survival.
Beyond the core saga, Klein joined Ordinal Scale’s augmented reality clashes, raiding bosses and engaging in events. His character radiates camaraderie and lighthearted humor, often diffusing tensions with wisecracks or earnest support. Though prone to comically bungled romantic overtures, his true focus remains steadfast—shield allies from harm, rally spirits in darkness, and stand unflinching when lives hang in the balance.
