My first thought was Shirayuki mistakenly thinking someone had returned from recon when in fact it was the new constructed ships reporting for duty.
This seems unlikely, however, given that Shirayuki herself had only returned to port based on Inazuma's subsequent comment.
Hence the current note.
Welcome home, Yuki-chan -nanodesu.How was the sea?We didn't see that "strong-looking person".At the moment, I've entrusted Hibiki-san with performing a patrol.
(Shira)...... Well,
for the time being.
(Shira)So... I guess it's safe to say the area's all clear now?
(Inazuma)Sigh...
Just when I thought I could relax after the reconnaissance.Even when I tell you there aren't many resources remaining, it seems you just don't understand the meaning of those words, my dear commander.
