Tsuyokute New Saga

In Tsuyokute New Saga, the ruthless Demon King commanded his monstrous legions to eradicate humanity. The valiant hero Kail, alongside his trusted companions, stormed the Demon King’s fortress in a desperate bid to end his reign of terror. Though they succeeded in slaying the tyrant, victory came at a devastating price—Kail lost everyone dear to him. Friends, family, lovers, and comrades perished in the brutal conflict, leaving him alone and mortally wounded. As Kail lay dying in the Demon King’s throne room, his fading gaze fell upon an eerie gem, an object the tyrant had obsessively guarded. Dragging himself toward it, he seized the artifact, triggering a blinding flash of light that hurled him years into the past. Stunned but resolute, Kail found himself in his younger form, determined to rewrite fate. Armed with foresight, he vowed to grow stronger and prevent the tragedies of his previous life from repeating.
