Isokaze's Kai and Kai B forms, main differences between this and her base from are listed as following:  
In her remodel, her scarf has been changed to a rope, her thighhigh gains a stripe, the Standard 12.7cm guns have been replaced by their High-Angle equivalent, a radar has been propped behind her head and finally, camo-textures are added to her uniform.

For her B remodel (which is not an actual second remodel), she is essentially the same as in her remodel except for her use of long 10cm guns. While she is now significantly more powerful stats-wise, the portrait serves as an art refresher.
