Heya no Soto de wa Dareka ga Waratteiru

At the very end of the world, a young boy stirs from his slumber to find himself alone in a desolate landscape. The remnants of civilization have long since faded, leaving behind only silence and ruin. As he opens his eyes to this bleak reality, his attention is immediately drawn to an inexplicable object resting beside him—a strange, gleaming orb that radiates an otherworldly light. In a place where everything familiar has been reduced to dust, this luminous sphere stands as the sole anomaly. Its smooth, reflective surface offers no immediate answers, yet its presence feels undeniably significant against the backdrop of total devastation. With no one else around to explain its origin or purpose, the boy is left to confront the mystery on his own. As he reaches out toward the shining artifact, the quiet emptiness of the ruined world seems to press closer. The discovery marks the beginning of an uncertain journey, forcing the lone survivor to navigate the remnants of existence while unraveling the secrets held within the peculiar orb that has appeared at the edge of all things.
