It's late autumn, the middle of November—the player (main character) is in his third and final year of his instrumental course at music school. The game takes place in the three months he has left until graduation.

The main character has been tasked with composing an original song for his graduation.

At the graduation recital, to be held in mid-January, it is stipulated that he must perform with vocal accompaniment. He needs to find a partner who will sing for him, but as usual, he hasn't even decided who that partner will be.

The aim of this game is for the player to complete an original song worthy of evaluation, and, at the same time, to find a vocalist partner―all before the middle of January.

The game is made up of "adventure"- and "music“-based parts. The game progresses as the player moves to various locations on the world map and watches the story unfold.

Throughout the story, you'll sometimes switch between the “adventure game” and “music game” parts.

In the “music game” part, you'll play minigames where you time your input on keys that correspond to letters written on musical notes appearing onscreen, which you may be familiar with from our previous games, Angelic Concert and Angelic Serenade.

It’s possible to reach a variety of different endings, which change in accordance with the choices you make as well as your “music game” results.
