Kashiko is a petite girl with a round face and pale hair, tinted a periwinkle blue, that reaches down to her shoulders, curving outwards at the ends. She wears it sideswept to the right, with one long bang hanging down beside her face which curls inwards, and she has the hair on the left side tucked behind her ear. Just like Momo Yaoyorozu, Kashiko is very responsible and has great leadership skills.
