Description
Noriyuki Izuna is an old friend of Kagura Tsuchimiya and the former fiancé of Yomi Isayama. He belongs to the exorcist Iizuna family, a lineage of spirit hunters, and serves in the information department of the government agency responsible for dealing with supernatural threats. He is a supporting character in the anime Ga-Rei: Zero, where his background and relationships are explored alongside the main narrative.

Outwardly, Izuna presents a perverted and cheerfully helpless demeanor, often attempting to grope Kagura with predictable and painful results for himself. This playful facade masks a deeply competent and powerful individual. Beneath his surface, he is highly knowledgeable about spirits and spiritual arts, skilled in creating barriers and using sealing techniques. He also wields a spear in combat and commands Kudagitsune, spiritual pipe foxes that he uses for reconnaissance and battle. His combat ability is significant enough to fight on equal terms with Yomi Isayama, one of the series' most formidable exorcists.

Izuna's motivations are rooted in his connections to the people he cares about. He treats Kagura like a younger sister, despite his inappropriate teasing, and shows genuine concern for Kensuke Nimura. His relationship with Yomi is the most complex; as her ex-fiancé, he never fully moves past his feelings for her. His lingering affection and guilt over her fate influence many of his actions. In the anime, he is portrayed as calm and cautious, often hesitant to act decisively because of his emotional ties to Yomi. This contrasts with his more flippant and humorous characterization in the original manga.

Throughout Ga-Rei: Zero, Izuna serves as a source of comic relief but also as a stable, knowledgeable ally. His role is primarily supportive, providing intelligence, strategic advice, and direct combat assistance. His development is tied closely to Yomi's tragedy. The guilt he carries for failing to save her drives him to make significant sacrifices later in the broader story. In later events, he is fatally wounded while protecting Yomi, is subsequently revived as a corrupted soul, and eventually becomes a free-floating ghost who continues to aid his friends.

Notable abilities include his mastery of the Kudagitsune for both spying and offense, his expertise in barrier creation and sealing arts, his proficiency with a spear, and his extensive knowledge of the supernatural world. Despite his lighthearted exterior, he is a powerful exorcist whose skills make him a valuable asset to the agency and a loyal friend to those he protects.
