Kimi to Oboreru Eden no Yoake

Koudai is an ordinary high school student whose life takes an unexpected turn when he reunites with Shiro, a childhood friend he once harbored deep feelings for. Their joyful reunion is abruptly cut short by a startling revelation: Shiro belongs to the dangerous underworld as a "Sentinel," and Koudai himself possesses supernatural abilities as a "Guide." In this hidden world, Sentinels are burdened with heightened senses that push them to the brink of death unless they maintain physical contact with their Guides. Unable to survive without one, Shiro demands intimacy from Koudai to stabilize his condition, leaving the young Guide shocked and overwhelmed by the sudden ultimatum. Driven by possessiveness and desperation, Shiro declares that he would rather claim Koudai than allow anyone else to touch him. As the two surrender to their physical needs, genuine emotions begin to blossom beneath the surface of their arrangement. What starts as a necessary survival mechanism slowly transforms into something far deeper. Koudai finds himself consumed by a fierce desire to rescue Shiro from the perilous underworld that threatens to destroy him, but escaping its grasp may prove far more difficult than either of them ever imagined.
