Samuel divided their team the same as before but now with the addition of Haru, they are more even.
Samuel left with Leyan and Kiara. While Clyde is with Kei and Haru. Nobody opposed the division because they all already knew how Clyde fought so they could be sure about his strength.
"You just have to protect Kei. I'll be the one at the front."
So Clyde said before they started moving deeper into the ruined city. Kei and Haru carry equipment for setting traps in their bags which they will gradually set up.
Samuel already knew quite a bit about the situation they would find themselves in. They didn't know where the party would appear so setting traps in multiple places was the best option.
The ruins of this city were indeed quite extensive. But they still have one week so they can do it gradually.
