kuma kai ni (kancolle)
The second remodel/kai ni of Kantai Collection's Kuma, as seen in Danbooru post #4301299 and Danbooru post #4301281, released on January 13, 2021.
Rather ironic for a lead ship, Kuma was last of her class to be given her official second remodels, Kai-Ni and Kai-Ni-Tei (D).
Standard
Kai-Ni (Danbooru post #4301299) has her wear a stylized serafuku consisting of a white short sleeved sailor blouse with a green sailor collar, a red neck ribbon, white culottes (essentially a pleated skirt with a divided section), and black boots as well as upgraded machinery.
Tei
Her Kai-Ni-Tei form (Danbooru post #4301281) changes the color scheme of her serafuku to an orange shirt with a black sailor collar and black culottes. This form also trades the ability to equip seaplanes and torpedoes with carrying midget submariness and daihatsu. She was sometimes grouped with Tenryuu and Shiratsuyu as having sisters who received second remodels before being remodeled themselves.
