Beyond the Boundary

The story is a dark fantasy centered around Akihito Kanbara, a high school sophomore who seems human but is actually half-Youmu, making him nearly invulnerable thanks to his rapid healing. His life takes a turn when he encounters Mirai Kuriyama, a lonely freshman who appears ready to jump from the school rooftop. Mirai is shunned by others, especially those in the spirit world, because of her forbidden power to control blood. After Akihito saves her, strange and unsettling events start to unravel around them.
