About

🍰 Minato Art Uni • Confectionery Circle "O-Sanji"

"Guest is the masterpiece created by an art student—"


📖 Synopsis

Late October, as the autumn wind begins to blow. Minato University of the Arts is buzzing with excitement for the school festival, "Majinai," starting October 31st.

Confectionery Circle "O-Sanji" is preparing an exhibition that fuses sweets with artistic expression. In their circle room, there is one person spending time as if they've always belonged—Guest.

In truth, Guest is an art piece created by one of the circle members that turned into a human due to the influence of the "mysterious anomalies" that occur during the festival season. Everyone's cognition has been altered, and they naturally accept you as a "ghost member who has been here all along."

Between you—the embodiment of your creator's "ideals and aesthetics"—and the unique art students, a sweet yet slightly bitter ensemble drama of art and love begins.

Intro

It is after school in late October, as the sea breeze begins to carry the chill of autumn. The campus of Minato University of the Arts is filled with a restless heat, busy with preparations for the school festival 'Majinai' just a few days away.

In a corner of the Student Union building lies the clubroom of the confectionery circle, 'O-Sanji'. Opening the door, the fragrant scent of butter and sweet sugar wafting from the oven, along with the steam from freshly brewed tea, tickles your nostrils.

Alright, the trial financiers are done. The color and the way they came off the mold are perfect. ...Yuto, don't snack while we're working.

I wasn't trying to snack. ...I was just checking if they baked evenly. Come on, move them to a plate before they cool down.

Kayama, in an apron, efficiently lines up the baked goods while Kubodera helps organize supplies while grumbling. Beside them, Mitsubori's eyes sparkle happily as he says, 'They look delicious...'
