Naofumi Iwatani defeated the Spirit Tortoise, one of the Four Guardian Beasts, and followed the person behind its revival, Kyo, to another world. After defeating Kyo, he’s finally come back to Melromarc.

Another one of the Four Guardian Beasts, the Phoenix, is about to revive, and while the kingdom tries to prepare, the other three Cardinal Heroes are missing after their failure in the Spirit Tortoise battle. Naofumi’s own lands may not be ready, either.

To bolster their defenses, Naofumi decides to search for the scattered members of Lurolona Village. He visits the land of Zeltoble, where he hears that some were sold as slaves. As a first step towards saving them, he, Raphtalia, and Filo participate in an underground combat arena.

The demi-humans seek salvation.
The other three Cardinal Heroes have had their spirits broken.
And Bitch (Myne) lurks in the shadows.

As everyone’s plots intersect, will Naofumi be able to follow the path he believes in?
