Why Does Nobody Remember Me in This World?

A young man named Kai belongs to an agency that protects humanity. While out with his childhood friend Jeanne, a world-changing event suddenly occurs.

Kai frees the captive winged girl, who introduces herself as Rinne. As they talk, a grotesque enemy suddenly emerges from a portal and attacks them.

Jeanne and the Resistance fight through the demon-infested government palace. Kai eventually comes face-to-face with the Dark Empress Vanessa.

Kai and Rinne struggle against Vanessa's overwhelming power. On the verge of defeat, Rinne undergoes a beastly transformation and strikes back.

Having retaken the royal capital, Kai and the others head east toward the Io Federation — the rulers of which are said to be more cunning than humans.

Commander Dante goes missing in the Forest of Elves. While searching for him, Jeanne and the others inadvertently pass through a teleportation gate.

In the Angel Palace, Falin's group and Rinne face their respective angelic opponents while Kai and the others confront the arrogant Alfreya.

As Kai battles Alfreya's avatar and the Angel Palace begins to crumble, Reiren and Jeanne look for the perfect opportunity to strike.

With Reiren in tow, Kai and his allies head south toward the Yurun Federation. While the group rests at a spring, Jeanne talks about Rasterizer.

Guided by the mysterious voice, Kai, Rinne and Jeanne enter the strange shrine. They soon reach a statue of a goddess and receive a divine prophecy.
