In a world overrun by monsters known as "Darklings," a young man named Tsuyoshi, who lost his parents, was making a living by scavenging items to support himself and his younger sister. However, one day, upon finding a strange item called the "Boundless Ring," Tsuyoshi was suddenly transported to another world, where he found himself on the brink of being executed by beastmen!

But just as his soul cried out, "I don't want to die" and "I want to be a hero," the "Boundless Ring" began to glow, granting him an incredibly powerful body and he got his hands on the beastmen's sacred treasure, the "Divine Hammer." Witnessing this turn of events, the King of the beastmen declared a challenge. If Tsuyoshi could train himself and become the hope of the beastmen within a year, he would be spared from execution. He already has no other way left than to move forward and grow stronger.

Can Tsuyoshi survive and thrive in this otherworld, overcoming the trials that await him?
