They got finished just before lunch, so Cain and the girls stop along the way back to the house to grab takeout. They've got a little over an hour before the next group, but after all that running, a shower is a necessity along with eating.
If they didn't have anyone with them, Cain would have just sent the groups led by Vala and the Oath Breakers on their way and stayed by the door to have a picnic and play cards. The summons don't sweat, let them do the running.
But that would be a bit overkill when leading a raid, and lead to inflated expectations, so they'll have to do it properly in the future.
They finish the boxes of beef and noodles as they reach the house, finding a few early arrivals already present. One of them recognizes Misaki, so they disappear together to chat while they wait. The group is almost all arrived before Cain gets out of the shower and heads down to greet them.
