Before they had reached the old side of the mountain, General Senju, who had witnessed all of this from start to finish, felt stuck between a rock and a hard place.
His mission was to join Nobuharu and Kohana to bring the Langford Queen alive and also to find out more about Nobuharu and his supposed party of accomplices for the Emperor.
