Finishing the battle with Kyo, Naofumi and his friends return safely to their world. The queen of Melromarc wishes to reward Naofumi for saving the world from the Spirit Tortoise. "Then can I have my own land?" After thinking about what he could do for his friend and partner, Raphtalia, Naofumi decides the best thing for their future would be the establishment of their own settlement–and he decides to build it on the ruins of Raphtalia's old hometown! The start of a whole new chapter in our hero's life begins here, in volume ten of this otherworld revenge fantasy!

The Shield Hero Naofumi and his allies have been caught up in a strange phenomenon and sent flying back into the past, village and all. Naofumi enters into an uneasy alliance with Mamoru, the Shield Hero of the past, but Naofumi remains unable to completely trust him, suspicious of his actions. One night, one of the orphans under Mamoru’s care comes to find Naofumi. The child proceeds to lead him to a chamber below Siltran Castle. “What kind of facility is this?” Just what has Mamoru been gathering up these orphans for? The action continues in the twenty-first volume of this still rising otherworld fantasy!

The otherworldly fantasy continues! Naofumi finally gets his revenge! But there’s a new problem: the heroes discover a dragon hourglass in an underwater shrine. They end up fighting a massive inter-dimensional whale, but nothing could prepare them for what happens next!

The long-awaited climax of the battle against the Spirit Tortoise has arrived! With Ost’s guidance, Naofumi and the others have descended deep into the Spirit Tortoise’s body to face off against the mastermind behind it all. But will unexpected guests interfere?

“I wasn’t expecting you to be in cahoots with the queen, that’s for sure.” Having defeated Kyo and left Kizuna and the others behind, Naofumi and his friends return to Melromarc. The Spirit Tortoise has left a deep scar on the world’s nations, including their own Melromarc. Now with the objective of preparing for future struggles against the waves and the deadly Phoenix, for some reason Naofumi heads straight to the slave trader?!

Naofumi Iwatani, an uncharismatic Otaku who spends his days on games and manga, suddenly finds himself summoned to a parallel universe! He discovers he is one of four heroes equipped with legendary weapons and tasked with saving the world from its prophesied destruction. As the Shield Hero, the weakest of the heroes, all is not as it seems. Naofumi is soon alone, penniless, and betrayed. With no one to turn to, and nowhere to run, he is left with only his shield. Now, Naofumi must rise to become the legendary Shield Hero and save the world!

“It sure has changed since the last time I was here.” A deadly illness has spread from the dragon corpse left unburied as a tourist spectacle. The shadow of death falls over the village to the east. Following Wyndia’s wishes, Naofumi and Motoyasu head there to try to put a stop to the plague. But the attitude of the villagers, who want a scapegoat for their misfortune, push the heroes to their limit . . . The heroes, seeking a proper burial for Gaelion and Wyndia’s father, head to the site of the corpse—only to find it transformed into a dragon zombie!
