Ai no Kusabi (2012)

Riki returns to his gang after three years as a pet, facing Iason's manipulative trap.

Riki, leader of the Bison gang, was kidnapped three years ago by Iason Mink, a Tanagura elite. He recently returned to Ceres, reuniting with his former partner Guy while hiding his past. Riki develops a strong dislike for new member Kirie, who lures the gang into a bodyguard job for transferred pets. Riki meets Katze, Iason’s former Furniture, who warns him about Tanagura’s secrets and urges him to flee. Ignoring the warning, Riki allows the gang to accept Kirie’s offer. The group is ambushed and arrested by Midas police, but Riki is released because his pet registration remains active. Kirie is betrayed by Iason and forced to become a pet. Iason visits Riki, demanding he return to Eos Tower or face imprisonment for his friends. To save Bison, Riki agrees to resume his role as Iason’s pet, severing ties with Guy and angering his former lover.
