Hari Kurono, alias Chronostasis, functions as the trusted right-hand man to Kai Chisaki (Overhaul) within the Shie Hassaikai yakuza. He exhibits fair skin, thin dark eyes, and sharp pointed eyebrows, complemented by distinctive chin-length pale hair styled into arrow-like "clock needles" reflecting his Quirk. His standard attire features a black plague mask with gold trim, circular glasses, and a long white raincoat consistently worn with the hood raised. Chronostasis maintains a composed, cold-hearted, and analytical demeanor. His unwavering loyalty to Overhaul remains absolute, extending to tacit acceptance of the leader's violent acts—including subordinate executions and Eri's inhumane treatment. This devotion manifests as complete subservience; he never challenges Overhaul's methods, instead relentlessly advancing goals like Eri's recapture or eliminating operational threats. His primary ability, the Quirk "Chronostasis," enables him to extend his arrow-shaped hair to strike targets. The front strand (minute hand) slows a target's movements for one minute, while the rear strand (hour hand) immobilizes them for up to an hour, though extending his hair demands absolute stillness. Beyond this, he wields a handgun firing specialized darts laced with a temporary Quirk-destroying drug and carries a concealed knife for close combat. Tactically, he excels in stealth and analysis, demonstrated by infiltrating a meeting undetected to snipe League of Villains members. During the Shie Hassaikai raid, he deduced Mirio Togata's Quirk impairment and blinded the captive Eraser Head to nullify his Quirk-erasing ability. As Overhaul's direct subordinate and an Eight Bullets leader, Kurono shares a close, trust-based dynamic with him, addressed familiarly as "Chrono." He prioritizes Overhaul's safety above all else, instantly intervening during the League of Villains confrontation. Training involves honing his Quirk on moving dummies to improve accuracy and speed, acknowledging its impracticality for live teammate exercises. Key events include his debut during the Shie Hassaikai's introduction, active participation in their conflict against the League of Villains, and involvement in Eri's retrieval and escape attempt during the raid. In that raid, he engaged Mirio Togata but was overpowered. Upon regaining consciousness, he immobilized Eraser Head with his Quirk and attempted to kill him before Tamaki Amajiki subdued him. His final narrative role concludes with apprehension by heroes during Overhaul's defeat.
