Δlice is a seemingly normal girl with short messy brown hair and tan skin with a pointed ahoge atop her head. She wears a white tiara and a black bow on the left side of her head. She sports a white-collared desaturated blue polo shirt with white buttons. The sleeves appear to be damaged by tears. She wears a black necklace with a bronze transparent triangle crossed through by two lines on it. Her attire is finished with a black tea-length skirt with a white waistband, white semicircle outline designs on the end with dots in between the mounds, accompanied by white socks and black Mary Janes. She appears to have a reddish scar on each leg. Partially Transformed: While Δlice‘s appearance mostly remains the same, part of her true form shows. Her clothes seem more tattered and ripped. She dons a tattered capelet with a brown patch appearing on the right side of the poncho with a rhombus symbol on it and a bandage wrapped around both of her sleeves. She still has a black bow but on the right side of her head. The white princess tiara changes to a black crown, and a strange red rash appears on the right side of her face. The top part of her face is obscured, thus only one eye is visible. Six small black spikes poke out from behind her, one of them wrapped in a bandage. Her left leg is covered in three cuts and scars, and she appears to accessorize a black legcuff on her right ankle. Her black skirt has two brown patches with a rhombus and stitches. As seen in a few artworks, she also has a bandage wrapped around her chest. True Form: At the end of Basics in Behavior, Δlice is seen in her true form. She takes on a demonic appearance, pitch black and silhouetted with bright red scleras and black slit pupils. Six large black spikes poke out from behind her, and three long tendrils occasionally extend from her back. She has long black claws, and she also has a long black tail. Additionally, she appears to grow in height, as depicted in official artwork where she is much taller than Oliver.
