Fuyume Hanamura is a member of the unit 'Special for Princess!' under 'NEW DIMENSION.' He is a boy with blind and selfish tendencies. Once a famous cosplayer in the amateur scene, he possesses a strong obsession with how he presents himself to others. While he believes he knows himself best, he shows a willingness to spare no effort for the sake of S Sagiri, whom he wants to become the ideal idol for. Fuyume lives in his own world and desires to be a "princess." He is skilled in sewing and general housework and loves fairy tales, giving him a healing image on the surface. However, much of this is part of a calculated image-making process conscious of how others perceive him. That said, his love for fairy tales is genuine. He is highly conscious of others' gazes and refers to himself in the third person as "Yume." He also prefers to be called by his nickname, 'Yume.' S Sagiri is the leader of the same unit and a childhood friend whom Fuyume blindly loves and is obsessed with. According to the unit relationship chart, Fuyume views S as a substitute for S's deceased father, describing this as the "lingering scent of a loved one." He projects another person onto S, asking S to show more of his anger because it resembles that person, or saying he wants to "travel to the stars in the sky where that person sleeps." There are mentions that Fuyume might know more about S's father than S himself does, making his blind love resemble a maternal obsession rooted in feelings for S's father. However, he harbors resentment that S does not always take his side. His fellow unit members include Natsu Kanna and Raika Hojo. Raika Hojo has praised Fuyume as a fan since his cosplaying days, but Fuyume shows a dismissive attitude, having little interest in anyone other than S. He is polite to those he likes, but treats others somewhat harshly—speaking informally, ignoring them, or giving them selfish nicknames. When things don't go his way, he may use harsh language, refuse to compromise, or fail to consider others' perspectives. However, he is still a child in the process of growing, capable of self-reflection and offering apologies afterward.
