Zōsui

Fair-skinned and grey-eyed, with pupil-less irises, Zōsui keeps his black hair combed back to shoulder length beneath a Kusagakure headband. His outfit runs to a kimono-style shirt in dark brownish grey edged with cream, dark trousers, and a white robe knotted at the waist, finished with black socks and sandals.

He comes across as detached and icy, his loyalty reserved entirely for the growth and success of Kusagakure. Willing to wring every use out of the people around him, he saw the two Uzumaki women purely as a means to mend his village's wounded, and offered a grieving Karin no comfort when her mother died, pressing her at once to shoulder the same healing burden.

When two remnants of the Uzumaki clan arrived in Kusagakure, the village agreed to shelter them on the condition that the mother lend her healing gift to the sick and injured, and Zōsui was placed in charge of watching over her and her daughter. Once war broke out and the mother collapsed from healing far too many at once, he swiftly ordered the girl to take her mother's place. He is only ever glimpsed inside Karin's Infinite Tsukuyomi dream, where he lies dead, so his fate in the waking world stays unknown.
