The group within the temple went their separate ways to prepare for the task at hand.
Kurokawa and Tadashi left first to go to their respective schools, clearly to inform their students that they'll be leaving for sometime and to of course brace them for the potential risk of invasion.
It was better to keep them in the know if an unwanted element appeared within their vicinity, there was no need to force the entire responsibility of protecting the village onto only the elders.
Haruna left to go to her own school where once more she was greeted by her kids and Shoichi who was continuing his training and refining the ability to hold onto the shape of the aura around his blade as another sparring session against her children came to a close.
