Togaru Kamakiri, alias Jack Mantis, trains as a Pro Hero in U.A. High School's Class 1-B. His distinct physique features pale yellow-green skin, a bright green mohawk, and mantis-like hooked blades extending from his cheeks. Standing 189 cm tall with an athletic build, he wears a dark green hero costume comprising a rugged cloak, black trousers, boots, and an eye-covering mask. Kamakiri embodies a hot-blooded, aggressive demeanor, openly craving combat—especially against rivals like Katsuki Bakugo from Class 1-A. He shows impatience during strategic planning, favoring direct clashes, as when urging teammates to "carve 'em up" in the Joint Training Battle. Despite this intensity, he displays camaraderie by comforting defeated classmates and framing losses as growth opportunities. He maintains a gym partnership with Tetsutetsu Tetsutetsu and pursues insect collecting as a hobby. His Quirk, Razor Sharp, allows him to generate exceptionally sharp, durable bladed projections from any body part. These blades slice through steel pipes and withstand point-blank explosions. His combat reflexes prove formidable, demonstrated when blocking Bakugo's explosions. U.A.'s Ultra Analysis Book rates his capabilities: Power B+, Speed B+, Technique C, Wits C, and Sharpness A. Kamakiri debuted in the U.A. Sports Festival Arc, participating in the cavalry battle. He later joined Class 1-B's wilderness exercises during the Forest Training Camp Arc. His pivotal role came in the Joint Training Arc, battling Bakugo's team and witnessing Setsuna Tokage's defeat, after which he consoled her and teammates while emphasizing resilience. In the Final War Arc, he aided evacuation efforts at U.A. before appearing in the epilogue as a graduate working professionally as a hero. Born on January 7 in Nagasaki Prefecture, his surname's kanji translates to "scythe" and "cut," while his given name means "apex"—collectively referencing a praying mantis. This design drew inspiration from entomologist Jean-Henri Fabre's studies. Post-graduation, Kamakiri achieved his goal of becoming a Pro Hero.
