Shuu Tsukiyama was the infamous Gourmet ghoul of the 20th ward. He was a fourth-year student studying Social Welfare at the Department of Human Sciences at Seinan Gakuin University. He comes from the extremely wealthy and influential Tsukiyama family which his father, Mirumo Tsukiyama was the head of. Tsukiyama himself became the head of his family after the Tsukiyama Family Extermination Operation. He was also a member of the Ghoul Restaurant, known as MM until he betrayed them.
He joined Kaneki's group with the hidden intention of eating Ken Kaneki, obsessed with his scent and taste but eventually came to genuinely care for Kaneki. Two years later, his severe depression and anorexia after Kaneki's apparent demise left him emaciated and required constant care from his family servants. After finding out Kaneki was alive and meeting him, he recovers, being able to walk and eat on his own as well as take measures to help Kaneki regain his memories.
