Ixphoria

Ixphoria is a former B-rank and current SS-rank difficulty world tasked the Goddess Ristarte to save as punishment.

History
100 years before the event of the story, Ixphoria the B-ranked world was tasked to Ryuuguuin Seiya who was under the guidance of the Goddess Ariadoa. The reckless but talented Seiya quickly progressed through the world; defeating any and all enemies despite the odds. His party continually complained of his recklessness, though he managed to reach the final step to clearing the world.

Before taking on the demon lord, Seiya was given advice that he could learn the Demon Lord's secret from the sages' village afar from his main path. Not wishing to waste his time, the reckless hero dismissed the advice and took on the demon lord. As with all enemies, the party defeated the demon lord. However, the victory was short lived. The apparent victory turned into horror after realizing the true secret of the Demon Lord; revival once after death. Surprised, helpless and exhausted; the entire party perished one by one through the jaws of the Demon Lord with Seiya having to witness the consequences of his actions before his own eyes.

With the Heroes' defeat, the demon lord grew in power and turned the world into a living hell.
