A Fallen Seraph's Last Hymn

Arashi Kageyama is just an archivist. Or so he thought. Quiet, thoughtful, and burdened with a strange sensitivity to the world’s emotional undercurrents, Arashi lives in Meirōmura, a village forgotten by time. But beneath his calm exterior lies a dormant power tied to something far greater than himself. When monsters known as Hollow Ones raze his village on the night of a cosmic event called the Harmonic Convergence, Arashi awakens to the terrifying truth: he is the reincarnation of Raziel, the Seraphic Keeper of Secrets, a being of forbidden knowledge and divine resonance. This revelation does not go unnoticed. Mizuki Shirasu, a disciplined Chorister Knight from the nation of Lumina, is dispatched to investigate the Resonance spike caused by Arashi’s awakening. Though their alliance is uneasy, Mizuki begins to question everything she’s been taught about the Seraphim, and the boy she was ordered to control. Together, they flee from corrupted creatures and the enigmatic Silenced, hunted by both holy and unholy powers. The deeper they journey, the more Arashi is forced to confront visions of his past life, the pull of ancient knowledge, and a growing dissonance in his soul that could either save or unmake the world. The Void Choir, a cosmic threat long erased from the records, is returning. And Arashi may be the only one who can stop it… if it doesn't consume him first. Now, Arashi must master his Resonance, uncover the truth behind the Divine Fragments, and choose between the secrets that could restore balance or unravel the last song of creation. What do you do when the universe sings your name... but every note is a warning?
