kuroshio kai ni (kancolle)
Kuroshio received her kai ni on the June 13, 2018 update. Uniform-wise, her footwear gets replaced with rudder-heeled boots, she gains a thigh holster on her left leg, her hair becomes slightly longer and her hairclips change to resemble Oyashio's. The most notable change is in her machinery, with her weapons changing markedly, her torpedo tubes now having their dedicated reload locker, and her gaining a mast.
