OVA
Description
Dr. Kasuminome operates as a scientist within the covert Dress Organization, specializing in biological weapons development through unethical experiments. His methods subject animals to extreme environmental stressors like severe temperatures and low oxygen to force adaptation. Survivors are bred, producing monstrous offspring optimized for combat. His most significant creation is the Baoh parasite, a genetically engineered organism designed to transform hosts into powerful biological weapons.

Physically, he appears as a mature man of medium build. He possesses a long head, wrinkled face, puffy eyes, and is bald, sporting a mustache. He consistently wears large round glasses. His attire changes with the situation: suits during transit operations, dark kimonos within his secret laboratory disguised as a temple, and a lab coat during scientific procedures.

His personality is cold and ruthless, showing no remorse for his work. He orders the killing of test subjects' families to prevent inquiries, as demonstrated by the murder of Ikuro Hashizawa's parents after selecting the boy as a Baoh host. Following Ikuro's escape six months after implantation, Dr. Kasuminome immediately dispatches assassins to eliminate the teenager, fearing Baoh's uncontrollable potential despite his underlying admiration for its power. He operates with detachment, executing insubordinate agents like Dordo and warning lab personnel to evacuate before initiating the facility's self-destruct sequence.

His actions drive significant conflict. After Ikuro and the psychic child Sumire escape from a Dress transport train, he employs escalating measures to recapture or kill them. This includes torturing Sumire with intense noise to exploit her psychic link to Ikuro, using her as bait to lure Baoh into a trap. He sacrifices personnel without hesitation to achieve objectives. Faced with Baoh's imminent containment failure within his laboratory complex, he activates its self-destruct mechanism as a last resort.

His expertise lies exclusively in biological weapons R&D; he possesses no physical combat abilities or psychic powers. His intelligence is solely directed at creating and controlling mutated life forms, with the Baoh parasite representing his pinnacle achievement. This parasite grants hosts superhuman strength, agility, regeneration, hardened skin, and specialized offensive capabilities termed "Armed Phenomenon."

His story concludes within the collapsing Dress laboratory. Escaping via a pod during the battle between Baoh and the berserk psychic assassin Walken, he falls into an underground cavern caused by Walken's powers. During Baoh's final confrontation with Walken, a laser beam severs a stalactite that impales him. Facing death, he laughs, declaring that his demise and Baoh's presumed destruction will terminate the Dress Organization's research into the parasite.
