Martha the servant girl's idea was the trigger to start a new plan to finally arrest Erick Smakusa. Banishing him from the council, which brings together the commanders of the eight largest families in the Broteforge Empire.
Since this could be a longer plan than all the others, and since everyone was inspired by Martha's words, the huge group living in Ayumi's residence decided that they should fragment to act more widely.
Not everyone in the group were adventurers with powerful Gene Skills, so they decided to form a division among themselves, to prioritize exactly how safe everyone was.
This meant that powerful people like Luke Lange and Alexis Dmitry couldn't work together, which made them both upset. Still, the half-wolf didn't martyr himself too much over this, because he could still be paired with Meredith or Ayumi.
