Genius Prodigy Jade Carter falls into the zero-survival SSS-rank instance Bloodmoon Manor. To survive, she plays dumb and is kept as "Little Jade" by the instance boss Black. While pretending, she collects clues, successfully clears the instance and returns to reality, but Black is on the verge of losing control after her departure. Jade returns to the instance with the Carrot Anchor, anchoring the weakened Black into a black cat. The two enter The Repository, collect Obsession Fragments from monsters, resolve the Titus crisis, and build Crescent Manor to contain obsessions. The Mirror Citadel crisis follows. Jade and Black complete a permanent mutual Anchoring, repair the seal, resolve the hidden danger of the Eternal Night instance, the second door quietly opens, and a new adventure begins.
