Upon reaching the staging area, Kazu begins questioning those who had already been down in the tunnels and uses what information he can get from them, as well as his own acute sense of smell to hopefully find exactly which tunnel leads to the breach in the wall. With the information he is able to gather he heads down <Insert Tunnel Direction Here> with his blade drawn to help light the way. His twin daughters flank Melody in to prevent her from being overwhelemed in the event they are ambushed while Strelok follows in the shadows.

Making a lot of assumptions in the interest of moving this along so feel free to correct me if necessary, if we can't get any good leads towards a specific tunnel to go down, i suppose we'll start with the east tunnel if Katana has no objections. As for the rolls...
