Inspired by the mythic fox, Nine Tails blends design, intelligence, and purpose into everything we create.
About us
The name Nine Tails draws inspiration from the mythological fox — intelligent, adaptive, and evolving with each “tail” representing a new domain of mastery.
Nine Tails Corporation exists to bridge the physical and digital worlds through innovation that empowers people to grow stronger, think smarter, and live more securely. Each venture—Darkside Café, Kleos, and LockBoy—represents a unique expression of that philosophy, shaping how we move, create, and protect what matters.
By combining craftsmanship, technology, and purpose-driven design, we create experiences that foster mastery and independence. Whether it's a morning ritual, a personal breakthrough, or peace of mind in privacy, Nine Tails exists to make every moment an evolution toward something greater.
