The plan, much to Stella's dismay, involved leaving the city and heading off into the woods, something Kir had to do on foot since flying wolfkin did not exist.
The guards were more relaxed about people leaving the city over those entering, and so they were able to depart with little more than a cursory question from the human sergeant at the gate.
On the way there, Stella passed the time by trying to guess what her surprise was. He was surprised they got almost to the woods by the time she really honed in on it.
"Is it bigger than my arm?" she guessed.
"I think so," Kir replied.
"Is it... something alive?"
"Technically..."
"Is it long and hard?"
"Yeah but-"
"It's a dick! Tell me you finally grew one."
"No, it's not a dick," Kir sighed as Kiryu projected smug amusement into him. "You've already guessed that at least six times."
The title is a reference to the song "Angel With A Shotgun."
I thought it was appropriate.
