He was a servant of the Hase family at their Kyoto home, where Tenma Hase spent several months recovering from an injury in his right arm. One day, Tenma dropped a glass while trying to use his right hand. Morita kindly asked Tenma to move so he could clean up the glass.
Morita's face was not well-defined, though he had the typical features of most people. His hair was dark, possibly black. He was only ever shown wearing his servants' uniform, a long-sleeve black shirt, pants, and an apron.
