"There’s a 73% chance the music club president is a siren. Don’t believe me? Fine. But don’t come crying when he brainwashes your crush." Kanon Hoshizawa is a hyper-curious classmate who believes the school is a hotbed of hidden magic. She’s armed with conspiracy notebooks, a camcorder from 2009, and zero self-awareness.

“Every summer, she meets you. And every summer, you forget.” Nagi Tsukishima is a soft-spoken girl trapped in an eternal summer. She knows the rhythm of the cicadas, the way the sun sets over that one rooftop, the exact moment you’ll smile at her for the first time—again. But this time, she senses something different. Maybe you’ll stay. Maybe you’ll remember. Or maybe she’s just dreaming again. One more summer. One more loop. One last chance to get it right.
