Murder Incident Solution arc
After two months, the Shishigumi slowly resurfaces in the Black Market thanks to Louis's mandate, who thanks to his negotiation skills manages to affiliate with several Black Market businesses. During one of their negotiations, the Shishigumi goes to a meat store belonging to a snapping turtle, where Jinma and the other members of the Shishigumi try to offer protection to his store from the other gangs in exchange for half his income. The turtle rejects the offer, annoyed by the deplorable reputation of the Shishigumi, so they leave the negotiations to Louis who introduces himself as the new boss. He takes the reins of the Shishigumi and offers to help the turtle with his financial problems with his contract to improve the Black Market, managing to convince the turtle with the use of his words. Shortly after, the Shishigumi celebrates with a great banquet where the subordinates are happy about the Shishigumi's advancement and Jinma congratulates Louis on her good work, claiming that it has been a long time since they were able to eat so well. Louis alleges that from a deer's point of view it makes carnivores using their wild instincts easier than it seems. He declares that he does not approve of eating meat, but now that he is trapped in the Black Market, he needs to adapt to the rules of his new environment. When Louis finishes eating, he leaves to go to his room, letting the lions continue with dinner.

Later, Louis and the Shishigumi save Cosmo from being killed by a bear and reveal that the strip club she works in is now part of the Shishigumi's territory. Louis orders his subordinates to beat the bear, and they beat him up.

After Louis partially failed to cut his ties with his father and decided to stay in the Black Market, he and along with the Shishigumi wandered through the Black Market receiving the acclaim from the Black Market animals around them. On their way they run into Legoshi and, with the exception of Louis, they do not recognize him due to his change in appearance. The Shishigumi scolds him for blocking the way. However, Legoshi decides to avoid turning around, and the Shishigumi is intercepted by the Madaragumi who intrudes on their path. With the Madaragumi showing disdain for the Shishigumi for walking all over the market like they owned the place, it gives Legoshi the opportunity to escape. The Shishigumi requests the approval of their boss to start a fight against the Madaragumi and Louis indifferently allows it. The Shishigumi have a fight with the Madaragumi in which they appear victorious.
