Naotsugu was a veteran player of Elder Tale and a core member of the Debauchery Tea Party, an elite raiding group that tackled high-level content without being bound to a guild. His role as a Guardian made him a key player in difficult battles, as he could absorb enemy attacks and protect his teammates while allowing Shiroe and Nyanta to strategize and deal damage.

However, two years prior to the events of Log Horizon, Naotsugu quit the game to focus on his career in the real world, leading to the Tea Party’s disbandment. His departure left a lasting impact on Shiroe and others who had fought alongside him. Despite this, when he returned to the game for the latest expansion, he was thrown into the chaos of the Catastrophe, reuniting with Shiroe and Akatsuki, and ultimately becoming one of the founding members of Log Horizon.

Throughout the series, Naotsugu remains one of Shiroe’s biggest supporters, accompanying him on major raids such as the Abyssal Shaft Raid Party and the Shibuya Raid Team. His strength, humor, and loyalty make him an irreplaceable part of the guild, acting as both a protector in battle and a morale booster for his comrades.

Naotsugu is a tall, well-built man with short brown hair and an easygoing expression. His appearance reflects his cheerful and energetic personality, as he often smiles and cracks jokes even in tense situations.

As a Guardian, he wears heavy armor and carries a large tower shield, making him one of the most physically imposing members of Log Horizon. His sturdy, knight-like attire reinforces his role as the team’s frontline defender, allowing him to withstand attacks that would otherwise take down his allies.

Naotsugu is boisterous, carefree, and outspoken, often serving as the comic relief within Log Horizon. He is known for his lighthearted and sometimes inappropriate humor, frequently making offhand comments about women and underwear, much to Akatsuki’s annoyance. However, beneath his playful and mischievous nature, he is deeply caring and highly dependable, always looking out for his friends.

As a Guardian, Naotsugu takes his role seriously, willingly putting himself in harm’s way to protect his allies. He has a strong sense of loyalty, particularly toward Shiroe, whom he follows without question. Though he often teases and jokes around, he understands the weight of their situation, knowing when to step up and provide emotional support to those in need. His optimistic and reassuring presence serves as a stabilizing force in the guild, keeping morale high even in dire situations.

Despite his casual and carefree attitude, Naotsugu is highly experienced in combat, possessing excellent reflexes and tactical awareness. He may appear goofy on the surface, but he is one of Log Horizon’s most battle-hardened warriors, proving time and again that he is not just comic relief—he is a true leader on the battlefield.

• Reuniting with Shiroe and Founding Log Horizon
  After the Catastrophe, Naotsugu reunites with Shiroe and quickly proves his reliability as a tank, becoming one of the first members of Log Horizon. He provides both combat support and emotional reassurance, acting as the glue that holds the group together. His ability to keep spirits high makes him an essential part of Shiroe’s plans to stabilize Akiba and form the Round Table Alliance.

• Supporting Shiroe and Akatsuki
  Alongside Akatsuki, Naotsugu serves as one of Shiroe’s closest allies, following his plans without hesitation. Though he often clashes with Akatsuki due to his teasing, he deeply respects her as a fighter and considers her a close friend. His unwavering support reinforces Shiroe’s confidence, ensuring that Log Horizon remains united even in the face of overwhelming challenges.
