Cautious Hero: The Hero Is Overpowered but Overly Cautious

Mash and Elulu demonstrate some new skills they picked up, and Aria is horrified to learn that Seiya is training with Mitis. Back on Gaeabrande, Rosalie has gone off to challenge the flies alone, and Seiya and company must go to her rescue.

A delegation of Roseguard Imperial Knights summons Seiya and the others to a nearby fortress, where a wing of demon houseflies is attacking from the air. Seiya offers his help, but when he butts heads with the knights' leader, things turn ugly.

Elulu and the others are stunned that she is supposed to offer her life to become the ultimate weapon for defeating the Dragon Lord. The party reluctantly agree to go through with the ceremony, but trouble erupts when they have second thoughts.

Following Mash's recovery, Seiya agrees to allow him and Elulu join them on the adventure, but insists that they receive more training first. The pair offer to lead the party to a cave called the Dragons' Den, said to contain an ultimate weapon.

With a massive undead army approaching, Seiya dismisses any assistance from Mash, who does not take kindly to the snub. However, when Mash later turns up missing, it is up to Seiya and the others to rescue him from the enemy's clutches.

After Rista and Seiya retreat once again to the Divine Realm, Aria proposes that Seiya train under the tutelage of one of the Gods there. A looming crisis on Gaeabrande compels the pair to return, and seek out companions to aid them in their quest.

Chaos Machina proves too much for Seiya and Rista, and they retreat back to the Unified Divine Realm. However, when Machina takes the entire town hostage, the pressure is on to come up with a way to stop her before more people get hurt.

A goddess named Ristarte is given the task of saving a world with an S-ranked difficulty level. She summons her champion, a man named Seiya, whose abilities are off the charts, but whose overly-cautious personality may give her second thoughts.
