The Hero Is Overpowered but Overly Cautious, (Novel) Vol. 32017

Well, this probably isn't the kind of homecoming anyone expected... After saving the Gaeabrande, Seiya and Rista are rewarded (or punished) with a one-way trip to Ixphoria. Due to their failure to save the B-rank world in the past, the baddies have leveled up and plunged Ixphoria into chaos, transforming it into an SS-Ranked Hellscape! And just when it seemed like things couldn't get any worse, Seiya falls victim to a class-changing curse! Now the Overly-Cautious Hero must save this impossibly difficult realm as...a playful piper...?
