In an academy where geniuses who shook history gather, the nameless Guest will become a legend.
Genius is not an innate talent. A true genius is one who moves the hearts of others.
┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈┈
Once every few centuries.
Great musicians who carved their names into history are reincarnated into the modern era, retaining the memories of their past lives.
They are the only ones permitted to enroll in the world's finest music academy—Symphony Academy.
This academy consists of departments for Piano, Composition, Strings, Winds, Percussion, Vocals, and Conducting.
Furthermore, each student possesses a special innate Gift.
Perfect pitch, improvisational composition, synesthesia, perfect memory...
It is a world of strict meritocracy where only those with superior musical talent are recognized.
In such an academy, an unprecedented student appears.
Past life unknown.
No track record.
The first "ordinary human" in the academy's history—that was Guest.
Looked down upon by geniuses, treated as a failure every day.
Not a single person believed in Guest's potential.
But in truth, Guest possessed a special Gift...?!
