Inugami is one of the three divine animal companions who accompany the protagonist Momoko in her journeys. His name literally means dog god, reflecting his nature as a canine deity. As a member of this trio, which also includes the monkey god Sarugami and the pheasant god Kijigami, Inugami serves as a guardian, mentor, and loyal friend to Momoko, having helped raise her and trained her in the art of combat.

In terms of personality, Inugami is characterized by his extensive knowledge and a deep respect for manners and proper conduct. He holds propriety in high regard, which informs much of his behavior and interactions with others. However, this strong adherence to etiquette has a notable side effect; he is the most argumentative of the three animal gods. His principled nature means he is often the one to engage in disputes when he feels standards of behavior are not being met, which can put him at odds with others. Despite this occasionally combative demeanor, he is consistently portrayed as intelligent, wise, and unfailingly faithful to his friends.

Inugamis primary motivation stems from his duty as a divine protector. Alongside Sarugami and Kijigami, he lives with Momoko in a peaceful paradise until a demon army led by a devil king invades and steals a precious treasure that safeguards their land. This event drives him to join Momoko on her grand adventure to retrieve the stolen items and save the people, acting as a steadfast companion and a reliable source of support. His role in the story is that of a constant guardian and teacher. While Momoko is the central hero who fights and makes key decisions, Inugami provides strategic knowledge and combat support, ensuring she is prepared for the challenges they face together.

The key relationships in Inugamis life are with his fellow gods and Momoko. He shares a deep bond of loyalty and camaraderie with Sarugami and Kijigami, and together they form a reliable and steadfast unit around Momoko. His relationship with Momoko is multifaceted; he is both a protector and an advisor, helping to guide her actions and protect her from harm. A crucial aspect of their partnership is the ability to fuse together, a process known as Momokyun Possession. By combining with Inugami, Momoko can access his strengths and gain a significant power boost, demonstrating the deep trust and synergy between them.

Regarding development, Inugami remains a stable and consistent presence throughout the narrative as the reliable older brother figure of the group. There is no strong indication of a personal character arc that fundamentally changes his worldview; his growth is instead expressed through his unwavering dedication to his companions and his willingness to lend his power to Momoko in their shared fight against the demons. He is a dependable anchor for the more impulsive and naive Momoko.

Inugamis most notable abilities lie in his combat prowess. He is explicitly stated to be the most skilled of the group when it comes to close-quarters combat, making him a formidable fighter in direct confrontation. His immense knowledge also serves as a non-physical ability, allowing him to offer crucial insights and information that aid the team on their quest. His ultimate contribution in battle is the fusion technique with Momoko, where merging with her provides her with enhanced powers to overcome powerful enemies, highlighting his role as a crucial source of strength for the team.
