Summary:

When the boundaries between worlds align and their frequencies resonate, a rare phenomenon known as “Resonance” occurs—creating portals between dimensions. Childhood friends Tachibana Reika and Takahashi Jin unknowingly trigger this event by touching the ancient artifact Tenkai Kyuka at a forgotten shrine in current day Japan, transporting them to the mysterious world of Yohara. Reika arrives centuries before Jin and awakens to her latent divinity, transforming into a powerful and feared figure. By the time Jin appears, she has become a merciless Yokai Empress, ruling with a cold, godlike presence.

As the supernatural forces of Yohara stir and the balance between worlds begins to collapse, Jin is faced with an impossible task: to reach the humanity buried deep within the one person he once knew. Torn between memory and power, Reika walks a path of destruction, while Jin’s presence may be the last light guiding her back. In a world of gods, demons, and ancient secrets, their bond is tested as fate, memory, and war converge.

Summary:

Resonance is a dark fantasy tale of power, fate, and the fragile thread of humanity. When Jin and his childhood friend Reika are pulled into a brutal, demon-infested world, he finds himself caught between warring factions, ancient forces, and a woman who is no longer who she once was. As Reika reigns as an all-powerful goddess, feared and worshiped in equal measure, Jin must navigate a world of chaos, betrayal, and shifting allegiances—while confronting the question that haunts him most: is there anything human left in her, or has she become something beyond salvation?
