There are less than 20 days left until this year's fireworks festival. In previous years, this is when Kagiya would test fireworks on the outskirts of Edo, where there are no buildings or crowds.
Aoto speculated that the sound of fireworks he and Mukiwa heard just now was likely the sound of Kagiya testing fireworks that they would set off at this year's festival.
"...17 days left, and this year's fireworks festival will begin, from August 23rd to August 25th. It's rare to have it for three consecutive days."
"Yes, it is." Aoto took a sip of tea, responding absentmindedly.
"...Aoto, do you have the evening of August 23rd free?"
"Hmm? I..."
Aoto was about to instinctively reply, "Hmm? I'm free," when he suddenly realized something and abruptly stopped mid-sentence.
The evening of August 23rd... isn't that the day of the fireworks festival?
Aoto's expression became peculiar as he put down his teacup and turned to look at Mukiwa beside him.
Mukiwa's face was normal initially.
