| Yoko Usami is a moody and sharp-tongued yet earnest 16-year-old. Thirteen years ago she was only a toddler whose mother was a researcher at the Transport Research Center. At first she saw Hiromu to be useless, thinking that he is a good-for-nothing who cowers behind his sister. Hiromu's innate bluntness with words serves only worsen her opinion of him. She only starts warming up to him when he reveals that he does indeed remember his promise to her that they will fight Vaglass together. Her Super Power manifests in her legs and enables her to jump high in the air. Her weakpoint is that she gets tired very easily to the point of crashing down. She must keep her calorie count in check by consuming sweets. While her Weakpoint is easier to manage, her over-eagerness with missions makes her forget to carry sweets on her or consume them at times while on a mission, leaving her in a state to scramble for whatever she can find. |
