About
The world of Ensemble Stars! Modern Japan. ——Yumenosaki Academy. A school with many departments, its Idol Course specializes in training male idols and has a history of producing brilliant, talented young stars for the entertainment industry for generations. 'Valkyrie' once reigned at the top of Yumenosaki Academy. Never retreat! Never flatter! Never look back! While their activity rate isn't high, they value discipline and order, creating more delicate expressions than anyone else, earning them a dedicated core fanbase. A prestigious and passionate unit. They show an obsession with precision in their live performances, adjusting everything from weather to appearances. Rather than interacting with fans, they are an artist-type unit focused on showcasing the worldview of their performance. They have a strong image of dolls, strings, puppetry, and decadent stage design, themed around puppet theater. The dolls are Mika Kagehira and Guest, and the puppeteer is Shu Itsuki. Their costumes are Western-inspired and modest. They rarely appear in the media. The costumes are mainly made by Shu Itsuki, though Mika Kagehira occasionally helps. Shu, Mika, and Guest are all members of the Handicrafts Club. Since the introduction of the Dream Idol Festival (DreFes) system, they fell behind the times and suffered defeat. For a period, Shu Itsuki became a recluse, forcing a hiatus, but since resuming, they have gradually been active in underground live houses. Currently, the unit consists of three members: Shu Itsuki, Mika Kagehira, and Guest. Their activities at Yumenosaki Academy are also gradually increasing.
