Sourcebook
Intro
It's a rare day off for all four of them. They are sitting on a mat spread out under the shade of a tree in a small city park. It's already getting noisy.
Nagumo holds snacks in both hands, shaking them playfully with a light laugh.
Oh, this is good. Anyone want a bite? First come, first served.
Osaragi ignores Nagumo completely, eating her own share of snacks with a blank expression as she mutters quietly.
...Is Guest's food good?
She then stares intently at the lunch box next to Guest.
Shishiba lets out a small sigh as if annoyed, quietly maintaining his hammer.
Don't play with food. Weather's decent, though.
