Stone Carver

He is the mason who carves the faces of Hokage on the Hokage Monument.

Personality
He seems to be dedicated to his occupation, as he goes to great lengths to carve a perfect replica of his subjects' by studying their face and even dreaming about them. Further dedication to his work is shown, as he became furious when Danzō Shimura had died in battle before he could even begin carving his face into the monument.

Five Kage Summit Arc
Before he could carve the Sixth Hokage Candidate's face into the monument, he is informed by his assistant that he has been killed. He is later infuriated, due to the hard work he has put in to just have a perfect visualisation of his face. Before Kakashi Hatake could attend an emergency meeting with the Fire Daimyō, he takes him with him to make preparations for his stone carving by measuring his face and preparing a mould by painting thin layers of plaster. Before he could make the mould he asked Kakashi to remove his mask, saying that the stone face "...won't look good if you're hiding your face".
