Joke is known for her cheerful and outgoing personality.
She also wears an orange bandana and her costume sometimes includes a white hygiene mask with a circular smiley-face protrusion on either side. Below this, she wears a white V-shaped belt, and on her hands she has padded yellow gloves with golden plates over her knuckles and lower fingers, which extend in orange-striped tubes down her lower arms, with thick metal cylinders acting as wrist-guards over the top. Her hero costume consists of a sleeveless navy blue shirt with a high collar that’s buttoned up all the way to her chin, puffed shorts with a green and orange pinstripe design and a corset adorned with yellow smiley-face pins, dipping down in a shallow 'U' in the center. She has dark green eyes with bright pupils, but by far her most prominent feature is her unwavering joyous smile. She has sea-green hair that reaches just past her shoulders, and short fringe with splayed ends which is usually obscured by her bandanna. Emi is a young woman of a strong athletic build with noticeably muscular arms.
