Okitenemuru

Kanata and his friend Tokiji are ordinary teenagers navigating daily life in modern Japan, but their world is suddenly upended by a series of bizarre and gruesome deaths sweeping through their city. The victims suffer a horrifying fate: their heads grotesquely transform into animal visages before violently exploding. While these terrifying incidents initially remain nothing more than unsettling urban rumors, the nightmare strikes far too close to home when the phenomenon occurs directly at Kanata’s school. Caught in the chaos, Kanata awakens to a dangerous new power—the ability to "remove his limiter." This grants him the capacity to drastically amplify a single personal attribute, though the enhancement comes at a severe cost, as another one of his abilities spirals dangerously out of control each time he uses it. His life takes an even stranger turn when he encounters Shiki, a mysterious and beautiful woman clad in a black, skin-tight combat suit. She forcefully drags both Kanata and Tokiji deep into the heart of these inexplicable events. As they struggle to survive, the boys must uncover the truth behind the killings and identify the shadowy organization orchestrating them, stepping into the center of a sprawling, world-spanning conspiracy.
