verniy (saury festival) (kancolle)
The fishing-themed official alternate costume of Kantai Collection's Verniy.
For the annual Pacific Saury/Mackerel Pike event, starting in 2017, she wears a arctic-pattern camouflage jacket, earmuffs and black pantyhose instead of her thighhighs. She is equipped for ice fishing, with an auger, a bucket and a fishing rod. Upon being damaged, she wears her bucket as a helmet (a likely callback to her wearing a cooking pot on her head in the anime).
