Sensei is one of the League of Shadows' most senior members. He is also an associate of the Light, and directs the League of Shadows based on the Light's orders.[2]


As a habitual practitioner of meditation,[3][4] Sensei evinces remarkable levels of discipline and self-control. He is capable of keeping his temper during both verbal and physical altercations, and enduring intense pain, such as that of walking barefoot on molten magma. Sensei is also a ruthless assassin who will kill his opponents without hesitation. He is completely devoted and loyal to his master, and will chastise anyone who dares to show him the smallest sign of disrespect.[4]

Physical appearance[]

Sensei is an old, light-skinned man with white hair and dark brown eyes. He is completely bald on the top of his head, and the rest of his hair extends near his shoulders. His white mustache extends to his cheeks and under his chin. He has a large scar across his chest, and a smaller scar extending from his forehead to just under his left milky eye.
