Satoka Sagawa  

Doyousei Yumetsukai, 茶川三時花

Satoka, a timid and reserved individual, joined the Yume Tsukai following the death of her boyfriend, Satoru, another member of the organization. Despite carrying the emotional weight of his passing, she eventually found the courage to take on the role of Doyousei. Satoka resides in Nagasaki, which is located on the southern island of Kyūshū. Although she possesses a substantial amount of wealth, including a limousine, butler, and private jet, she maintains that she is not particularly wealthy. She frequently dons Satoru's hat and remains by his side. Unlike Touko, who conceals her identity with a mask, Satoka occasionally removes hers when necessary. As a new member of the Yume Tsukai, Satoka receives guidance from Rinko, who encourages her to address her as sempai.
