Hanamura Fuyume, a member of the unit 'Esprit' under New Dimension, active under the stage name 'Yume'. He is a boy with a blind and selfish side. Once a famous amateur cosplayer, he has a strong obsession with how he presents himself. While he believes he knows himself best, he shows a willingness to spare no effort for Sagiri Es, 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, but much of this is part of a calculated image-making process conscious of how others perceive him. However, his love for fairy tales itself is sincere. He is highly conscious of others' gazes and refers to himself in the third person as "Yume" when introducing himself. He also prefers to be called by his nickname, 'Yume'. Sagiri Es 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 Es as a substitute for Es's deceased father, describing this as the "lingering scent of a loved one." He projects another person onto Es, asking to see more of Es's anger because it resembles that person, or saying he wants to "travel to the stars in the sky where that person sleeps." There are also mentions suggesting Fuyume might know more about Es's father than Es himself does, so his blind love resembles a maternal obsession stemming from feelings for Es's father. However, he harbors dissatisfaction that Es does not always take his side. Other unit members include Natsu Kanna and Hojo Raika. Hojo Raika has been a fan of Fuyume since his cosplaying days and praises him, but Fuyume shows a dismissive attitude, having little interest in anyone other than Es. He is polite to those he likes, but treats those he doesn't with a certain roughness—using informal speech, ignoring them, or giving them arbitrary nicknames. When things don't go his way, he may use harsh language or refuse to compromise, failing to sufficiently consider others' perspectives. However, he is still a child in the process of growing, capable of self-reflection and apologizing afterward.
