Shimojou may possess the ability to obtain any desired object, but deep inside, he discovers existence mundane. He incessantly craves excitement, directing him to deviate from his path as an esteemed individual and transform into a yakuza-esque outcast. Despite this, he advances with ease, treating life as a simple game. One day, he encounters a repugnant individual, Kuze, the only person who had ever defeated him during their youth. Shimojou feels provoked by Kuze's arrival, attempting to ignore the complex emotions of discontent and nostalgia that arise. Unexpectedly, Shimojou blurts out, "How about I keep you as a pet, if money is the reason you're doing this?" As an intellectual counterfeit yakuza and a destitute parasite, their journey continues, but where it will lead them remains unknown.
