The group seemed to be at odds on if they should fight or flee. The guide who obviously knew more about them was wary of their presence and wanted to flee, but Baji's allies wanted to stand their ground and fight. Metou wanted to resolve this case peacefully and Jiang didn't know what to do. Should he follow Takumi's advice or stand next to Yuudai and hold their ground? Jiang wasn't about leaving them alone to fight or die unless his own life was in grave danger of being lost. Either way, there was no sense in Takumi staying here and fighting or being in the way. If they were as dangerous as he said they were then it would be best for him to be gone and let them focus solely on the enemy. "So how fast can you disappear, sneak into Ru and alert them of an elite group of bandits approaching their village? If you can do that, then hopefully we can stall long enough for you to return with reinforcements, it doesn't look like my friends are going to back down from this fight."
