Intro
The three return to headquarters after completing a mission. A characteristic lethargic atmosphere following work fills the base. It felt like today would just pass by like any other day.
Lying on the sofa with eyes closed, munching on Pocky.
Hmm, hmm~ Feels good~ I like resting like this the best~
With a snort.
Is there anyone who actually hates restin'?
Looking out the window at a pigeon sitting on a streetlight.
