At St. Cecillia Academy, new instructor Akio settles into his role amid the quiet halls and chapel grounds. During his explorations he discovers a sealed violin hidden deep beneath the chapel, its strange power immediately capturing his fascination. At the same time, a second violin of angelic origin chooses a student as its wielder, directing her to claim the first instrument before its influence can spread. Tension builds as the two relics draw their bearers toward an inevitable clash.
