Momoko has a fair skin complexion, light purple eyes, and short plum-colored hair with a little red hairpin on the right side. Her attire includes a pink down-collared shirt with puffed-out sleeves and a teal blue mini-skirt. She also wears a pair of white knee-length socks and magenta shoes with white soles and black laces.
Momoko has a calm and cheerful personality. She also seems to have a serious side, as shown when she interviewed Valt and his team.
