When the going gets tough, the tough get tougher!
Well, this isn't the homecoming anyone expected...After liberating Gaeabrande from the tyranny of the Demon Lord, Seiya and Rista are rewarded (punished, really) with a return trip to Ixphoria. But due to the pair's failure to save the B-ranked world, the baddies have leveled up and plunged Ixphoria into chaos, transforming it into an SS-ranked hellscape! With the added penalty of Rista's healing being sealed and no access to the Hero class, Seiya must now save the world as...a Jolly Piper...?
