Mui

Mui had long black hair that goes beyond his shoulders, though ten years ago, when he was trying to use Muku to open the Box of Ultimate Bliss, his hair was around shoulder-length. He wore some sort of suit with a brown belt and a silver buckle. He also wore brown boots. When meeting with other members of the Fruit Group, he donned the metal head of a bull and wore loose-fitting, black robes.

Mui's wife passed away not long after their son, Muku, was born, so he raised him all by himself. He was a caring father who loved his son deeply, often taking Muku to eat ramen. Ten years ago, as the guardian of the Box of Ultimate Bliss, Mui, tried opening it once with Muku's chakra, in the hopes of asking the box to grant them the wish of reviving Kusagakure to its former glory. However, Muku didn't have enough chakra and was sucked into the box instead, leaving Mui grief-stricken. As a result, he sought a way to reopen the box to ask for his son back, unbeknownst to his superiors.
