Roboko

She is a member of Zvezda and can be described as an autonomous, self-thinking robot created by the ancient Udo River civilization. She possesses a refined appearance as a female-type robot, and during her growth period, she can shed her body and transform into what seems like a golden-haired, blue-eyed girl, exuding a charm reminiscent of an anime protagonist. The single-lens camera eye installed on her forehead is usually hidden behind glasses, highlighting her intellectual demeanor. Apart from wearing a face mask as part of her basic Zvezda form, her appearance remains unchanged. She only consumes Udo-shaped special energy bars for nourishment, and only accepts those made from organic matter, making her an exceptionally unique creation. Additionally, due to her very delicate design, she can malfunction if exposed to large amounts of secondhand smoke, but since she is shown to take a bath with the Professor, it is presumed that she is at least somewhat waterproof. Furthermore, her fingertips can unleash a variety of attack methods, such as beams and water guns, and she frequently operates as if she were a television remote control, showcasing her versatility as another captivating trait. Incidentally, when she infiltrated West Udo River Third Middle School, she cleverly used the alias "Tsuji Roboko."
