Issa Inuzuka, a middle-aged military officer with a medium build, short black hair, a goatee, and piercing yellow eyes, commands as a colonel leading a specialized task force against interdimensional supernatural threats. His role merges strategic oversight with frontline combat, deploying advanced Yoroi powered suits to neutralize hostile entities. A calm, methodical leader, he enforces strict protocols and efficiency, grounding decisions in proven tactics from past missions. Though stern, he reveals unwavering loyalty and compassion toward allies, particularly Benio Myōjin, whose anti-oni team he supports without hesitation. His duty-driven resolve often clashes with protective instincts for imperiled civilians and younger comrades thrust into peril.

Beyond the battlefield, Issa nurtures a tender bond with his daughter Kanae, wrestling to reconcile paternal devotion with the demands of command. This duality fuels quiet struggles between obligation and personal ties.

Analyses align him with ESTP and ISTJ personality types, blending pragmatic adaptability with systematic problem-solving. As an Enneagram 8w7, his assertiveness and self-reliance coexist with a fierce protectiveness over subordinates. Combat mastery and tactical acumen cement his formidable reputation, though inflexibility occasionally hinders adaptability in fluid scenarios. A native of Mie Prefecture, his entrenched role in the series’ central conflict remains consistent across canonical sources.
