Hades

Managed by the mysterious Reaper, Hades is the place where Luka's memories linger and accumulate. It becomes accessible after the White Rabbit drops the access key in Iliasburg. Surprised by his sudden appearance, Reaper clarifies that Luka is the only one among his companions who can perceive the place.

Several activities can be performed inside Hades, including changing a number of game settings, fighting any defeated bosses and enemies, as well as challenging Reaper herself. Once chapter 2 has been cleared, it also becomes possible to access the Labyrinth of Chaos, and watch a teaser of upcoming events in chapter 3.

Upon death, Luka will also return to Hades, albeit a different version.
