The weekend right before summer break.
Or, to put it another way, the weekend right before the summer camp.
I had been called out by Irena-san, and now Nina-chan, Irena-san, and I were on a bus together.
The reason we were on the bus? To help out with Irena-san's work.
Well, calling it "help" might be a bit off.
I had gone to Nina-chan's house to practice Recollection Condense, and Irena-san was there. She casually invited me, saying, "I'm going to work this weekend; why don't you come along?" And it wasn't just going to be me and Irena-san.
Nina-chan, who had now learned to exorcise monsters, was coming with us too.
Knowing that Nina-chan would be there, and realizing it would be a good opportunity to improve my still-underdeveloped Recollection Condense, I decided to join them.
When I told my dad about it, he encouraged me, saying, "It's rare to get the chance to see fairy magic; you should go."
