Kazana Island… A cozy, cool paradise where summer never ends.

The protagonist finds himself stepping foot into this island paradise as a transfer student, greeted by a mysteriously glittering sky, as well as the energetic island caretaker Ame, a girl-type AI.

After a bit of a rocky start, he settles at the dorms where a handful of new female friendships await.

She’s a tomboyish beauty, but a bit of a loner: Himari Asamiya.

The manifestation of brains and beauty, and also student leader: Hazuki Murasaki.

The self-proclaimed “Daughter of Darkness”, with a normal side too: Io Kouzuki.

Always trying to act the grown-up, but still a tease (your cousin): Noeri Fujishiro.

And the girl who embraces her role of making everyone happy: Ame.

How will you sculpt your everlasting happiness here in paradise?

A new love is about to begin…
