Neptune, Compa and IF arrive here to at the behest of Chian, as a monster is blocking the trade route for factory supplies. Getting tired after trekking their way through, they stop to take a break for pudding, only for the target itself to appear and run their picnic. Activating HDD, Neptune declares the monster will feel her wrath for "tainting pudding time."

As they slay the great bird, Noire catches up and hides behind an outcropping. Hoping to regain her stance by defeating her rival, Noire activates her HDD and intends to ambush them. As the trio unsuccessfully tries to bribe Neptune into flying them back to Lastation in HDD form, IF spots Black Heart hiding behind the rocks.

Upon defeating her, Black Heart runs off with the others in pursuit. Changing back to Noire, she is suddenly grabbed by Neptune. Not immediately recognizing her due to being in a different form, Noire takes advantage of the confusion to feign amnesia and stay undercover.
