chikuma kai ni (kancolle)
Chikuma's second remodel.
In her remodeled form she wears a green top matching her unremodeled state except it is now more elaborate. Her belt now goes to her upper waist and her boots are no longer lace-up. The most noticeable change in clothing she gets is a long, black side slit skirt that creates a pelvic curtain. It also gives off the impression that she doesn't wear any panties. However, supplementary material for the 2016 anime film of Kantai Collection reveals she actually wears extremely highleg panties like her sister, with straps above the skirt slits.
