In the typical anime style, Saiko is an incredibly tall and skinny young adult with a curved figure and large bust, who towers above her love interest Fishy Boopkins. She has pink, curly hair with two different colored highlights at the tips: purple highlights on the right side, and yellow highlights on the left. Her eyes are purple and almond-shaped, with thick, curly lashes on the ends. She also has pinkish skin.

Saiko is always seen wearing a tan jacket with a black tube top underneath.
