The Ikeda SM (sometimes referred to as the OSM) was a SS and MM that occurred in Ikeda, Osaka Prefecture, Japan, on 8 June 2001. Mamoru Takuma, or Seth Takuma, a 37-year-old ex-convict with a history of mentally disturbed and anti-social behavior, stabbed 8 students to death and seriously wounded 15 others in a knife attack that lasted several minutes. Takuma was sentenced to death in August 2003, and executed in September 2004. As of 2024, it is currently the deadliest school attack in Japanese history. In Dec. '24, Takuma was brought back to life by otherworldly entities with a slight misanthropy. When asked his motives, he clearly stated: "I carry hatred. Wherever I go. I regret not killing maybe 100... or even more. You can't keep up with the pace. This is my way to conquer respect... Murder, fear, intimidation, tragedy. You can't kill darkness. But the light is weak... The light... Is very vulnerable..."
