Content Warning: This story contains graphic depictions of violence, intense emotional struggles, and mature themes. It explores complex character conflicts, dark fantasy elements, and supernatural themes. Reader discretion is advised. In a world where emotions shape reality, Yūgensekai is split between realms of light and darkness. Each place reflects the inner battles of its people-where fear can give birth to monsters, and hidden desires can tear lives apart. Kuru Aoshima is a young woman trying to find her place in this fractured world. With a past full of loss and mystery, she's on a journey not only to uncover the truth about the world around her but also about herself. She's haunted by her own doubts and struggles, torn between the darkness within her and her search for clarity. In a world where your feelings can turn into powerful, dangerous forces, keeping control isn't just a matter of survival-it's about holding on to who you are. Facing powerful enemies like Raikou Saito, the ruthless leader of a syndicate that trades in suffering, and Serena Akihara, a leader torn by her own inner conflicts, Kuru's journey is full of heartbreak, violence, and moments that test her spirit. As she fights for answers, she is constantly on edge, pushed to the limit, both physically and emotionally. Bloodied and broken, she refuses to give up. But in a place like Yūgensekai, where darkness and light are always at war, how much of yourself can you lose before you're gone forever?
