Time for a mafia butterfly cut... "Hey there, Mr. Assassin... why don't you turn into some sashimi for me?" "Once in a while, try being the one getting eaten instead of the one eating the sashimi." A combat specialist of the Kyogoku-gumi appearing in "The Tracks of Kyogoku." A madman who uses a unique fighting style combining Praying Mantis Kung Fu and a sashimi knife, he is known by the alias "Moriwaka of the Sashimi Knife." He is also called the "Inevitable Disaster of the Kyogoku-gumi." A few months before the Tenkyo War broke out, he was under house arrest for causing trouble, but his suspension was lifted to fill the gap left by Sosei Sagara, who died in the line of duty after being defeated by Sakutaro Iitoyo. At the time, the Kyogoku-gumi members were divided into the "principled faction" and the "renegade faction," but he was long considered a rare existence that fit into neither. He does possess a certain degree of common sense and cannot be called a renegade; he is cooperative with the principled faction led by Mitsumitsu Igarashi. However, his actions can only be described as abnormal. While he doesn't engage in dirty rackets like the former renegade members, he is undoubtedly the most troublesome member now that they have been wiped out. He has short light-brown hair and purple eyes without highlights, though they occasionally turn black. He wears an orange short-sleeved polo shirt and short chino pants. His features are neutral, handsome, and boyish—officially described as a "man like a boy." However, he frequently wears an eerie smile, making it clear to anyone that he is not a sane human being. He seems to be on the younger side within the group; Yasuaki Ichijo and Kaoru Sengoku speak casually to him, but since he speaks casually to Luke Kurobane, he is likely older than Luke. He is tall at 184cm, standing level with Takasago. He is one of the most prominent madmen not just in the Kyogoku-gumi, but in all of Human Bug University, which has featured a wide variety of lunatics. He possesses a bottomless madness, such as tying up low-level thugs over minor disputes and turning them into human sashimi without hesitation. Because he uses a sashimi knife as his weapon, he has a habit of peppering his conversation with fish names and technical terms for preparing ingredients. His humanity is extremely thin; he nonchalantly dismantles enemies like a factory worker while smiling innocently like a child. While other madmen could be categorized as "extremely eccentric," "excessive seekers," "those who surrendered to madness for their goals," "insane," "battle maniacs," or "incarnations of malice" within human bounds, he transcends those to be a "beast in human skin" or "something pretending to be human." Despite everything, he has stepped in to help Sako, and he showed a quiet anger upon hearing the news of the deaths of Tsuneyoshi Namioka, who was in his same year, and Ginji Ozono, the former young head. When he learned of the death of Shogo Kaise, a senior he got along well with, he honestly showed his loneliness at the funeral. During his homeless days after leaving CODE-EL but before joining the Kyogoku-gumi, he showed genuine gratitude when he was given food by the elderly men he spent time with.
