Watch Ai no Kusabi

While drinking at a bar, a frustrated Riki thought back to the events that lead to his meeting with Iason three years ago to where he was now: While pick-pocketing in Midas, a fifteen-year-old Riki is caught by Iason, who allowed him to go free on a whim. Unable to feel indebted to him, Riki invited Iason to a hotel and offered his body to repay him.

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.

Arriving to his home in Ceres, Riki goes to sleep on his first night of freedom. Meanwhile, Iason continued his duties as a Blondie and confirmed to Katze that Riki is no longer with him, although the latter assumed that Riki was killed. Traveling through Midas, Katze compared the greedy and lustful citizens to the slums mongrels, whom are looked down by others and must steal to survive.

Riki has a forbidden affair with another "pet" (human sex slave) and undergoes punishment from his jealous owner Iason. Reprimanding Riki while sexually stimulating him, Iason temporarily asserts control over Riki. Two years later, still rebellious Riki goes to the front gates of Eos Tower and reflects on how living in the slums of nearby Ceres had been better than his current pampered prison.
