Last Seven Days: Tenshi no Kegashikata

Shion has always admired his childhood friend Ibuki, frequently describing him as the picture of perfection. However, their ordinary lives are shattered when a mysterious voice from Heaven delivers a chilling decree: because Ibuki is such a good child, he will be taken from the world in exactly seven days. Simultaneously, Shion undergoes a startling transformation, sprouting feathered wings from his back and manifesting a halo above his head. As the divine countdown begins, Ibuki slowly starts losing his senses, slipping away from the mortal realm just as the prophecy foretold. Desperate to save his dearest companion from being claimed by Heaven, Ibuki resolves to "defile" Shion, believing that corrupting his purity might break the celestial mandate. With only seven days remaining until his most important person disappears forever, the two friends are thrust into a harrowing race against time. Their bond is pushed to its absolute limits as they navigate this impossible ultimatum, leaving them to face a heartbreaking question: if they finally fall in love on the very last day, what fate awaits them both?
