Kagekuri Kitan

For as long as he can remember, Hajime has been haunted by terrifying creatures that dwell within the darkness. These monstrous entities lurk just beyond the edge of ordinary perception, visible only to him. Living in a constant state of dread, he navigates his daily life burdened by an invisible threat that no one else acknowledges or understands. The shadows themselves have become a source of relentless fear, isolating him in a silent nightmare where he feels entirely alone against unseen horrors. His desperate reality shifts dramatically when he encounters a mysterious girl born from the very shadows he has always dreaded. Rather than threatening him, she offers an unexpected pledge: she will help him confront and overcome the terrors that have plagued his existence. This encounter serves as the catalyst for a profound transformation in his life. Instead of merely surviving his fears, Hajime is suddenly pulled into a hidden society operating far beneath the surface of the normal world. Thrust into the clandestine realm of ninjas, he must navigate a dangerous new reality where ancient secrets and shadowy conflicts await. With his enigmatic guide by his side, Hajime's journey evolves from a solitary struggle against phantoms into an extraordinary adventure within a secret world.
