Masato Kaibara, also known by the alias Snark, is a supporting character in the anime Ghost Hound. He is the husband of Sanae Ogami, the mother of one of the main protagonists, Makoto Ogami. Masato is an adult man with black hair and black eyes. His background is closely tied to the traumatic events that affect the central characters. He appears to have died while Sanae attempted suicide, though the exact circumstances are linked to the dark history of the Ogami family and a fire that destroyed their home. In the story, Masato is encountered by Tarou Komori in the mystical realm known as Kakuriyo, or the Unseen World, where he wanders under the identity of Snark. His presence there suggests a lingering connection to the living world and the unresolved traumas of the past. Masato's motivations are not deeply explored, but his actions indicate a protective concern for Sanae. He plays a role in the unfolding mystery, serving as a bridge between the physical world and the spirit realm. His relationship with Makoto is strained, as Makoto's mother abandoned him, and Masato is a reminder of that painful past. Masato ultimately dies in the fire at the Ogami residence while attempting to rescue Sanae. His abilities include the capability to exist and move within the Unseen World, a skill that ties into the series' themes of out-of-body experiences and spiritual exploration.
