Tsuyokute New Saga (LN)

The Demon King's conquest to eradicate humanity culminates in a final assault on his castle by the Hero Kyle and his allies. Though the Demon King is defeated, Kyle witnesses the tragic loss of all his companions – friends, family, lovers, and comrades. As he succumbs to his own fatal wounds, Kyle discovers a mysterious gem the Demon King had coveted. The story features a male protagonist, Kyle, who is a Hero with allies including childhood friends. He is described as a hard-working, calm, and clever protagonist, potentially seeking a harem and involved in politics, schemes, and conspiracies. The narrative includes magic, swords, demons, dragons, and elves, and follows a "weak to strong" progression with a romantic subplot and strong love interests. The story is adapted into a manga and anime, with elements of second chances and polygamy. The protagonist is intelligent, and supporting characters possess complex motivations, with one example highlighting a seemingly carefree friend whose true ruthlessness is revealed. Even the princess is portrayed as manipulative rather than a damsel in distress, actively seeking advantage. Despite some criticism regarding repetitive tropes and character focus, the writing and translation are generally considered good, with one reviewer preferring the story of the events prior to the hero's time rewind.
