Saruhiko Fushimi is a 19-20-year-old male born on November 7, making him a Scorpio. He stands 178 cm tall and has AB blood type. Originally a member of HOMRA, Fushimi betrayed the group to become the third-in-command of Scepter 4. His combat role utilizes throwing knives and a saber as primary weapons. Fushimi typically presents a cool-headed, lazy, and bored demeanor, often appearing listless and unmotivated. Despite this outward attitude, he demonstrates high competence in his duties. He usually avoids clan activities unless necessary but cooperates with minimal argument when required. His approach to objectives employs any method to expedite tasks, including drugging civilians or attacking former allies without hesitation, reflecting his ruthlessness. His relationship with Misaki Yata is notably contentious; Yata habitually uses the derogatory nickname "Saru" (Monkey). This dynamic stems from their fractured past, though they eventually reconcile and reestablish their friendship. In "K: Seven Stories - The Idol K," Fushimi is depicted with his signature glasses, knife-fighting skills, and lazy disposition. His abilities include superpowers and proficiency as a sword fighter.
