Suishou Kibougaoka (希望が丘 水晶, Kibougaoka Suishou) is a freshman of St. Cargo All-Girl Academy, and formerly one of the interns working as part of the Candidate Student Council.


Presumably, because she is a robot, Kibougaoka usually acts reserved and emotionless. She often uses the term "mechanically speaking” before stating a fact, and very rarely expresses her own opinions aside from the facts. She claims that she came to Hakoniwa Academy to learn more about the heart. Kibougaoka also speaks with a French accent.


Kibougaoka has short, light pink hair. Her eyes are a matching pink, and her pupils are each shaped as a "+" (or a cross hair) with a circle in the middle. She wears what is presumably the St. Cargo Academy uniform, including: a yellow vest and red tie on top of a white, short sleeved collared shirt, and a dark blue miniskirt. She wears a light blue armband, signifying her position as a Student Council intern, around her left arm. Aside from her face, Kibougakoa's entire body is covered in a futuristic material colored white and dark blue. She has white, mechanical, star-shaped objects on the side of her head, which are removable. When she wants to, Kibougaoka can extend four mechanical wings from her back to use as a jet pack, allowing her flight. Ten years later, Kibougaoka wears a short-sleeved top over a dress.


Kibougaoka was invented one year prior to the start of the series at the Mifune Institute by the director Ifu Mifune, as the twenty-third prototype of an autonomous humanoid android called Hope. She was eventually enrolled as a first year in St. Cargo All-Girl Academy's Ume Class during her trial period.
