Seven Princesses, Seven Very Different Voice Actors
Rather than trickling the cast out one princess at a time, the production revealed the full royal lineup in one go, according to Japanese entertainment news site Comic Natalie. Each princess comes with a clearly defined personality, and the casting plays to that.
Aya Yamane voices Flora, the easygoing, slightly spacey first princess who happens to be a gifted athlete. Yoshino Aoyama (Hitori "Bocchi" Gotō in Bocchi the Rock!) plays Kiara, the flower-loving second princess who lives to tease everyone around her. Miku Itō voices Claire, the third princess who is hopelessly in love with the idea of love itself.
Rounding out the tower: Ayasa Itō as Mia, the fourth princess who wants to act grown-up but scares easily; Kana Ichinose as Charlotte, the fifth princess who can't let dishonesty slide and serves as the group's voice of reason; Fūka Izumi as Yuka, the endlessly curious sixth princess who wants to research everything; and Rina Kawaguchi as Eliza, the seventh princess whose great passion in life is food.
No voice actor has been announced yet for Alec, the prince whose kiss sets the whole story in motion.
A Curse, a Kiss, and a Very Crowded Tower
Seven Sleeping Beauties is set in the small kingdom of Amaryllis, where a witch's curse has put the entire population to sleep. Alec, the third prince of another kingdom, arrives to wake the kingdom's princess, only to discover there are seven of them, and none will wake without a kiss. He kisses all seven. The princesses open their eyes, the rest of the kingdom stays asleep, and the prince and his seven charges start living together while looking for a way to break the curse for everyone else.
Fiok Lee launched the manga in Kodansha's Monthly Afternoon magazine in March 2023, and it has been a steady presence there since. Volume 12 is due out in Japan on July 16, 2026. The series arrived with notable backing from day one: when serialization began, Comic Natalie's launch coverage carried a recommendation from The Quintessential Quintuplets creator Negi Haruba.
The Team Adapting It
Mankyū is directing, with series composition and scripts by Keiichirō Ōchi (The Quintessential Quintuplets) and character designs by Masaru Koseki. Animation production is a joint effort between Studio Gokumi and AXsiZ SMASH.
In a comment published alongside the announcement, Mankyū said that when he first read the manga he was captivated by the pure innocence of princesses who had grown up sheltered inside their own small world.
The reveal also came with a teaser visual showing all seven princesses asleep and wrapped in thorns, a nod to the cover of the manga's first volume.
Looking Ahead
The anime is slated to premiere sometime in 2027. No season, broadcast date, or network has been announced yet, and there is no word on an international streaming partner. Kodansha has not announced an English edition of the manga, so for now the announcement itself is the main way overseas fans can meet Amaryllis's royal family. With the premiere over a year out, expect key visuals, a trailer, and the prince's casting to arrive between now and then.
