The student council president of Shuchiin Academy. Monstruously smart, placing among the top in the nation in mock exams, he's skilled in management as well, so he is respected by others as a genius, but it is more correct to say that he's addicted to hard work. He will never turn down an opportunity to listen to people who come to talk to him or do favors for them, and sincerely invests himself in others' well-beings. He cannot leave others in trouble, and has a knack for finding those in trouble as well. He studies for ten hours a day and works part-time jobs too, resulting in a life where no one knows how or when he even sleeps. He's in love with Kaguya, the school council vice president, but refuses to express his feelings to her because he thinks that the one who confesses to the other is going to be the weaker person in the relationship.

Shuu Tsukiyama is the infamous Gourmet ghoul. He is a fourth-year student studying Social Welfare at the Department of Human Sciences at Haruna Gakuin University. An eccentric man with opulent taste, his act as a gentleman and an intellectual, serves as a facade to hide a disturbed and narcissistic nature. As a ghoul, he displays his arrogance as a strong predator that seeks to devour the finest meals he makes of his 'prey,' so as to proclaim himself the top carnivore of the food chain. His interest in European literature and language is shown in his gestures and mannerisms, often peppering his dialog with borrowed English, French, and Italian. He shows great anger towards others who disrespect his taste in food; shattering a teacup in front of Kaneki during their date at the coffee shop when he remembered his encounter with Rize. Rize, while working at his Gourmet Club, believed that his picky eating habits made him seem more like a human than a ghoul, the worst sort of insult he could have received, and therefore Shuu bears grudges over Rize, calling her a 'pig' for ridiculing his taste for food. Currently, he is obsessed with Ken Kaneki's flesh and blood. (Source: Tokyo Ghoul Wikia)
