A Sinner of the Deep Sea

Although the ocean encompasses seventy percent of the Earth’s surface, its abyssal realms remain largely uncharted by humanity. Thousands of meters beneath the waves lies a hidden nation where the mermaid Jo has long enjoyed a serene and undisturbed existence. This peaceful life is abruptly shattered when her close friend Ryuu is imprisoned for violating the most sacred law of their underwater society: the absolute prohibition against revealing their world to humans. The severity of this transgression raises urgent questions about Ryuu’s motives and the identity of the human who received this forbidden knowledge. Driven by loyalty and desperation, Jo embarks on a perilous journey to uncover the truth behind her friend’s actions and secure her release. Her quest forces her to navigate both the treacherous politics of her own people and the mysteries of the surface world that Ryuu sought to bridge. As Jo delves deeper into the circumstances surrounding the broken taboo, she discovers that her mission to save her friend is inextricably linked to an unexpected romantic entanglement. This adventure becomes not only a fight for justice but also a profound exploration of love across the boundaries that separate two vastly different worlds.
