The last thing I remembered was that Ireena-san had left Haneda Airport, heading somewhere within Japan for her exorcist work.
I had assumed she wouldn't be back for a while and was busy with her assignments, yet here she was, in Tokyo, standing right in front of me at my school.
"You seem surprised, Itsuki-san," Ireena-san said with a knowing smile.
"...Well, yeah. It's hard not to be when you show up here out of nowhere."
Ireena-san's smile widened slightly, and she explained, "There's a spell known as Shunting. It allows you to exchange positions with a fairy. As long as you can manage the timing and handle the magical energy expenditure, it's quite useful. I used it to get here quickly."
Ah, I see now. It's similar to that teleportation magic I saw a monster use before.
