The next morning.
Fujino was just about to head out to ask around about Enomoto Azusa.
But before he could leave, a familiar big sister came knocking.
Sato Miwako arrived at Fujino's house. Today, she was wearing her usual light-blue suit paired with a slightly lighter-colored skirt.
She still looked like the same fierce woman from the workplace.
Before Fujino could head out, he ran into the fierce big sister who had come to his door and immediately teased her.
"Big Sister Sato, how many days have you been working nonstop this time?"
"There have been quite a few cases lately—the airship attack, some serial murder case, and so on..." Sato Miwako was not surprised by that, since the kid before her was a detective. Still, she asked curiously, "But how could you tell?"
"Your clothes," Fujino explained casually. "There are dirt stains and grease marks around your cuffs and skirt hem. Judging by those marks, you haven't washed this outfit for at least several days."
"Is that so?" Hearing that, she lowered her head, seemingly only just realizing it. Then, after a moment's thought, she smiled and teased him in return. "You really do pay close attention, kid. But how can you be sure that changing into another outfit wouldn't take much time?"
Fujino looked her over again. "Although you are a little lazy, Big Sister, and probably don't like doing laundry much, you're not lazy enough to keep wearing the same outfit without changing."
"Unless you haven't gone home these past few days."
"Or you've been too lazy to toss your clothes into the washer and hang them up, to the point where you don't have any formal clothes left to change into."
"..." Sato Miwako gave him a dead-fish stare. "You just called me lazy, didn't you?"
