The Imperial Seal grants unimaginable power to those deemed worthy by its own will. When Rikuson's family loses their sacred duty as the seal's guardians to the warlord Sonsaku, the young man reluctantly enters his service. His mission is simple: determine whether Sonsaku truly deserves the seal's blessing. Before answers come, assassins cut Sonsaku down and the seal vanishes once more, leaving Rikuson adrift in a fractured world. Now he must navigate the treacherous landscape of the Three Kingdoms era, where armies clash for supremacy and survival itself demands compromise. Every alliance carries the weight of hidden agendas. Every victory comes at a price paid by the innocent. As Rikuson searches for the seal and seeks to understand its true purpose, he discovers that power and destiny are far more complicated than duty or honor alone. The seal calls to those it chooses, but what does that calling actually mean? Set against sweeping battles and political intrigue, this story asks whether one person can change the course of history or whether history simply uses them.
