Cassia is working in the Capital as a sorter while Ky is in Camas training to be an Airship pilot for the Rising.

When Ky and Indie are placed on the same ship to deliver medical supplies to Grandia City, the leader of the Rising, called the Pilot, reveals that they are on a special mission to initiate the rebellion and bring the cure for the plague as the Society plunges into disarray.

In Central, Cassia forms a group of people willing to share their art and talents with each other called the Gallery.

The Pilot arrives, demanding a cure, stating that a faction in the Rising intends to usurp his position.

It is revealed that Indie died after her plane crashed when she ran out of fuel after realizing she contracted the virus and tried to leave.

Cassia goes to Keya to try and cure her sick parents because her mother can lead them to more Mariposa Lily and discovers her father is already dead.

Cassia has a realization that she unknowingly added Ky to the Matching Pool but could not remember because of the red tablet.

Ky and Cassia convince Anna to leave Endstone in order to run for office and represent the people rather than the Society or the Rising.
