Shattered Angels

Kuu Shiratori is a high school student living in Academia, a massive city that has become a symbol of humanity's recovery after a catastrophic event that occurred ten years ago. She's been having recurring dreams about a prince, Kyoshiro Ayanokoji, who asks her to leave with him. When the prince appears in person at her school, he repeats the same request he's made in her dreams: "Let's go... together..." The students are preparing for the school festival, but Kuu's encounter with the prince sets her life on a different course.
