Unrestrained Healer

In a world under threat from a powerful adversary, Thaden, a recently evolved and overpowered hero, finds himself free from Guild responsibilities and eager to explore higher-difficulty dungeons on his own. With only his squirrel companion Sadia by his side, he navigates new challenges, but the looming menace from the Adversary continues to grow. As the System deploys its own agents to combat the infiltration, Thaden faces the choice of whether to step into the conflict or remain on his solitary journey. Combining LitRPG, isekai, and portal fantasy elements, this story follows a formidable protagonist in a battle-filled adventure.
