Seiya Shinjuku

A charismatic and manipulative top host operating in Shinjuku's Kabukicho district, Seiya commands the nightlife scene with polished social skills and cold-blooded scheming. His plan to enslave Ayaka Toshima using an SCM device backfired spectacularly when she outmaneuvered him, flipping his predator role into that of prey. Passed between multiple masters and entangled in a complicated dynamic with his ex-girlfriend Juria Katsushika, he serves as a pivotal supporting character that exposes the brutal power reversals at the heart of the Slave Game.
