Saiki wears a pair of controller devices on his head, the devices resemble white, cyan antennae, with pink, lollipop-like spheres. Accompanying the devices, Kusuo wears white glasses with lime green lenses. His hair is a hot pink and his eyes are a softer pink. He’s always wearing an apathetic expression and only has a softer face when eating Coffee Jelly. He’s usually wearing the school uniform which is a white shirt, green blazer and green pants, which so match well with his glasses.
