Shiro Gasuki

Shiro Gasuki is known as the oldest individual ever accepted into the villain rehabilitation program. Despite his intimidating appearance, he carries himself with quiet composure and rarely raises his voice. His words, when spoken, are deliberate—each one weighed before it leaves his lips. At the time of his arrest, Shiro was involved in a street incident that spiraled into chaos. He released a vast cloud of his quirk’s powder, putting several people to sleep and drawing the attention of multiple heroes. His quirk, Somnus Dust, allows him to emit a fine powder capable of inducing deep sleep or full-body paralysis depending on its concentration. Though non-lethal, the effect is potent and unpredictable, leading to his classification as a high-risk individual. Despite his past, Shiro cooperates willingly with the rehabilitation program. Many younger inmates regard him with a mix of awe and apprehension—his presence radiating both wisdom and unease.
