Tsumugi Yamagata

Tsumugi Yamagata (, Yamagata Tsumugi) was an elderly human woman that worked as a tailor and mask-maker. She was a long-time friend of Uta and Yoshimura, providing her services to Ghoul clients.

Appearance
Tsumugi was an elderly woman in her 80s, hunched over and often described in unflattering terms by others. She claims to have once been an attractive young woman, though it's unknown whether this was true or simply a joke.

Uta
The two are long-time friends, and have a deep respect for the other as a fellow artist. Tsumugi is a mentor to the younger man, and teases him about his "awful" artistic style.

Asa
Initially, their relationship is very poor thanks to the young Ghoul's bad temper. But Tsumugi begins to teach the younger woman about sewing and craftmanship, under the guise of forcing her to do busywork. They develop a strong bond, almost becoming like family in the time they knew each other. After her death, she left everything to Asa and allowed her to begin a new life.

Yuujirou Utsumi
When they were young, the two were lovers. Though aware that he was a cannibal that preyed on young women, Tsumugi admits to finding his bold nature attractive. Eventually, they grew apart and went their separate ways.

Yoshimura
The two have known each other for some time, and have great respect for each other.
