Half a year has passed since Riki's return to Ceres, who is easing back into his life in the slums. While Riki participated in airbike race one day, Kirie suggested that Bison goes to see a Pet Auction that would be held soon in Mistral Park. Although Riki was uninterested, Kirie goaded him into going as Guy noted Riki's strange behavior. Meanwhile, Iason, who is still longing for Riki, is carrying out his duties as a Blondie in Tanagura. With the Pet Auction drawing near, Raoul invited Iason since he feels that it is time for Iason to attain a new pet, and Iason reluctantly agreed to go. Back in the slums, Norris, a member of Bison, advised Riki to settle things with Guy properly since he had never broken off his pairing with him when he "disappeared" from Ceres. Despite feeling guilty for leading Guy on, Riki could not bring himself to end his pairing with Guy.
On the day of the Pet Auction, Riki and Bison rode into Mistral Park discreetly as Riki's dislike for Kirie grows. During their tour, Riki and Guy reminisced about their time in Guardian, leading Guy to comment how Kirie was like Riki three years ago, much to Riki's annoyance. As they observed the pets on display, Riki and Kirie sparked an argument about the division between the slums and the citizens on Midas. Having spent enough time in the city, Bison decided it was time to leave, despite Kirie' objections. However, Riki spotted Iason's arrival and the two clashed eyes for first time since Riki's release, which caused Riki to have a panic attack and forced Bison to retreat. Kirie stayed behind to have an audience with Iason in hopes to find a way out of the slums. Once the auction was over, Iason, who recalled his unexpected encounter with Riki earlier that night, and ordered Katze to take Kirie as his underling without revealing to Katze of his plans.
