"Ah well, looks like I'll have to show off my Tenzai Ninjutsu again."
—Kogoro Tenzai

Kogoro Tenzai (天斎 小吾郎 Tenzai Kogorō?) is one of the two main protagonists of Project X Zone.

Crosspedia Entry[]

Ostensibly a private detective. In reality, he is a descendant of the Tenzai clan, ninja-for-hire since feudal times. As well as "working" as a private detective he is currently in the employ of the Koryuji family as the tutor of their daughter Mii. During battle he displays complete command of the fabled sword of the Tenzai, "Nyoraito," a giant shuriken on his back called "Sharinken" and the blades "Hassojin" attached to his feet by wires. He has also mastered the art of creating copies of himself. He has a little bit of an attitude and tends to avoid anything resembling hard work. Nevertheless he treats Mii with respect, calling her "m'lady."


As a leading protagonist, Kogoro first appears in Prologue 1: The Wanderers and reappears in Chapter 1: Welcome to the Koryuji House. Kogoro fights with Mii as his partner. The detective wields his primary weapon, the Nyoraito, in addition to a variety of ninja weapons hidden on his person and ninjutsu such as creating clones of himself and releasing flames from his fingertips.
