When we last saw our main characters, they had just defeated the Demon Lord of Gaeabrande, saving the S-ranked world for which Seiya was summoned. For sacrificing his life to defeat the Demon Lord, Seiya was resurrected a third time before being assigned a new world to save along with Ristarte. To go along with the revelation that Seiya and Ristarte were once lovers in a past life, the two are assigned the world they had failed to save all those years ago, Ixphoria.
However, according to the synopsis for the ensuing light novels, things aren't going to be quite the same this time around (via Cautious Hero Wiki). Because Seiya and Ristarte had failed to save it in their previous incarnations, it is now ranked "SS" in terms of danger. Furthermore, Seiya has been re-classed as a flute-playing bard. With new abilities in a (sort of) brand new world, Seiya's battle to save Ixphoria will be unlike any he has seen before. Still, the two are not dissuaded. All it takes is a little caution and preparation to get the job done.
