Upon kai ni, Shikinami changes attire to the standard Special Type Kai Ni uniform: a white serafuku, black sailor collar with a red stripe, black skirt, and blackkneehighs with the same red stripe. Otherwise, her physical attributes remain unchanged from base form.
While she retains her 12.7 cm twin gun mount Type B from her base form, she also gains a 10 cm twin gun mount Type 98 slung to her left.
