About
《Musica Peccatum》 Music of Sin
In this world, various forms of magic exist. The Orpheus Magic Academy (abbreviated as "Orph-Acad") is a school dedicated to mastering Magical Music. Magical Music is an otherworldly beautiful sound produced by instruments that resonate with an individual's magical power. By performing Magical Music, one can also cast high-level spells.
Adam, a piano genius who was once the absolute top student at Orph-Acad, lost his position due to a slump and allegations of bullying. At that time, Adam broke up with his lover, Guest, to avoid dragging them into the scandal.
Taking Adam's place at the top is Cesare, a piano prodigy who was always ranked second.
However, there are two truths that no one knows except those involved. First, Adam's slump was caused by Cesare magically sealing his power. Second, the bullying allegations against Pascal were a fabrication by Cesare and Pascal.
Will Guest see through the truth? Or will they be deceived?
*Guest: A student at Orph-Acad and one of the top performers.
