Inugami is a tall, well-built man with shoulder-length, fluffy yellow hair. The front portion of his hair falls to the right, partially obscuring his right eye. He has distinct droopy eyes that give him a calm and laid-back expression.

His usual outfit consists of a beige suit vest worn over a dark green, long-sleeved shirt, complemented by a green tie. He pairs this with matching beige pants and brown oxford shoes. At times, he is also seen wearing a beige blazer, a fedora hat, and oval-shaped glasses with rimless dark green lenses accessories that add to his composed and refined appearance.

In his tanuki form, Inugami’s fur is a mix of brown and yellow, reflecting elements of his human form’s color scheme.

Kohachi Inugami is known for his calm and composed nature, remaining level-headed even in high-stress or dangerous situations. He rarely loses his temper and often finds ways to turn situations to his advantage through intelligence, observation, and adaptability. Despite his laid-back and easygoing attitude, Inugami is highly responsible, particularly when it comes to the well-being of the children in his care.

As the head of the Inugami Detective Agency, he approaches each case with a practical mindset, resolving issues with efficiency and discretion. He avoids unnecessary confrontation but will step in decisively when needed especially to correct behavior or protect those he considers family. He plays a mentorship role for Kabane, Shiki, and Akira, offering guidance while encouraging their independence and personal growth.

Although generally tolerant even of difficult individuals like Mihai Inugami’s patience has limits, especially when the safety of his team is compromised. When provoked, his rare displays of anger can be formidable. Beneath his composed surface lies a strong protective instinct, and those who pose a threat to his found family quickly discover the extent of his loyalty and strength.

Kohachi Inugami is a Bake-danuki, a supernatural tanuki with the ability to take on human form. While much of his early life remains shrouded in mystery, it is known that he has long worked as a mediator between humans and Kemono, using his abilities and knowledge to maintain balance and resolve conflicts involving the supernatural.

Inugami eventually established the Inugami Detective Agency in Tokyo, a private organization dedicated to investigating Kemono-related incidents. Through this agency, he helps both humans and Kemono navigate the complexities of their intertwined worlds. His office also serves as a safe haven for young hybrids and displaced Kemono, including Kabane Kusaka, Shiki Tademaru, and Akira. Acting as both guardian and mentor, Inugami offers them shelter, employment, and guidance as they learn to coexist with their dual identities.

His decision to take in Kabane stems not only from a professional interest in the boy’s mysterious background and possession of the Lifestone but also from a personal sense of duty to protect and nurture those who are lost or rejected by society.

As a powerful Bake-danuki, Inugami possesses a wide range of supernatural abilities typical of his species, including shapeshifting, illusion creation, and advanced transformation techniques. His versatility in combat and utility makes him a formidable figure in both investigations and battle.
