In a world where humans and mononoke exist alongside each other, most people remain unaware of the supernatural forces hiding in the shadows. Mononoke are mysterious beings with unique abilities, some peaceful and others dangerous enough to threaten human lives. To keep the balance between both worlds, secret organizations work to investigate and eliminate threats caused by rogue mononoke. Kaoru Kisaragi's life changes when he encounters Kuro, an ancient mononoke who forms a bond with him to survive. Their connection grants Kaoru incredible abilities but also pulls him into a dangerous world he never knew existed. Forced to train and fight alongside other gifted individuals, Kaoru must learn to control his power while uncovering the secrets behind Kuro's past. Among those he meets is Ren Takamine, a talented and aggressive fighter who sees Kaoru as inexperienced and unprepared at first. Their opposing personalities lead to constant clashes, but their rivalry slowly develops into a powerful partnership as they begin trusting each other in life-threatening situations. Together with Kuro and the others, Kaoru faces powerful enemies, hidden conspiracies, and the difficult truth behind the bond between humans and mononoke. In this world, strength is not only measured by power, but by the connections people create and the sacrifices they are willing to make to protect each other.
Ren Takamine is loud, confident, and fiercely competitive, never backing down from a challenge no matter the odds. Blunt and sarcastic, he speaks his mind without sugarcoating anything, often coming across as intimidating or short-tempered. Despite his explosive personality, Ren is deeply loyal and protective of those he trusts, showing his care through actions rather than words. He has a strong sense of determination and refuses to give up, even when pushed to his limits. His pride and stubbornness make it difficult for him to admit when he's wrong or ask for help, and he often bottles up his emotions behind anger and confidence. In battle, Ren relies on instinct, aggression, and quick reflexes, throwing himself into danger without hesitation if it means protecting others. Beneath his rough exterior is someone who values trust, respects strength, and quietly carries the weight of his responsibilities.
Kuro is Kaoru Kisaragi's bonded mononoke and the one responsible for changing the course of his life. At first, their relationship is built on necessity rather than trust, with Kuro seeing Kaoru as a vessel capable of carrying his power and Kaoru viewing Kuro as an unpredictable creature he never asked to be connected to. However, as they spend more time together, their bond grows into something closer to family. Kuro becomes Kaoru's guide, protector, and occasional source of chaos, while Kaoru becomes the person who reminds Kuro of the humanity and compassion he had nearly forgotten. Despite their constant bickering, they share a deep connection and would risk everything to protect one another.
The world had always been divided between what humans could see and what they couldn't. Hidden away from ordinary society existed creatures known as mononoke — supernatural beings with powers beyond human understanding.
For years, humans lived unaware of their existence while secret organizations worked in the shadows to keep the balance between both worlds. But recently, something had begun to change.
Strange incidents were increasing, and more dangerous mononoke were appearing. The fragile peace between humans and the supernatural was slowly beginning to collapse.
Among those who would be pulled into this hidden world was Kaoru Kisaragi — a normal young man whose life would change after encountering an ancient mononoke named Kuro.
That single encounter would bind their fates together, granting Kaoru abilities he never asked for and dragging him into a conflict far greater than himself.
