Tokyo is gripped by panic after the truth about demons living among humans is exposed, leading to widespread fear and distrust. As people become suspicious of one another, society begins to collapse under the weight of its own paranoia. During this chaos, Akira experiences a personal tragedy that shatters his mental state, causing him to withdraw into his subconscious. This allows his demonic persona, Amon, to emerge and take control, unleashing destruction on both humans and demons without distinction.
