The 3DS version of Dragon Quest VIII: Journey of the Cursed King won’t end after the game’s main story is cleared. There will be an post-ending story that unlocks after you clear the main story.
Details on the new story are slim as to avoid spoilers, but according to Square Enix, it will reveal “a certain secret” related to the protagonist.
Screenshots show the protagonist standing in front of a door, beyond which this new story begins. There’s also an unfamiliar town where there appears to be no sign of life, suggesting there was some sort of incident.
After discovering a mysterious stairway, the protagonist will come across an unknown foursome of monsters, who fuse together to become a single monster of overwhelming strength.
Furthermore, within a dungeon, you’ll encounter a huge dragon that claims itself to be the Dragon God Sovereign (voiced by Kenjiro Tsuda). A “shocking truth” will be revealed after the fight, and the protagonist will not hide his astonishment.
This is unrelated to the new ending first teased in Jump magazine last week. Rather, it appears to be part of that “Ultimate Trial” dungeon with “Purple Treasure Chests” that opens up after clearing the game.
Dragon Quest VIII is due out for 3DS in Japan on August 27.
