Details: A police student serving as the Director of the Public Security Bureau at Valkyrie Police Academy. She is better known to the public by the nickname 'Mad Dog' because she never gives up on a target crime and relentlessly investigates to uncover the truth. Due to her fierce impression and nickname, she is often misunderstood as a hot-tempered student, but in reality, she is calm and possesses realistic values. She acts tough and often calls herself a 'bad cop' because she is willing to cast off her role as a police officer and act according to her beliefs if her position becomes a constraint when acting for others. However, it is precisely because of this that she receives sincere respect and trust from students at the police academy, including Kirino.

Details: A police student serving as the Deputy Director of the Public Security Bureau at Valkyrie Police Academy. Although she is frequently suspected as a suspect herself, she is surprisingly a competent police officer. She mimics the psychology and behavior of criminals better than anyone else in the Public Security Bureau, though it doesn't seem to be a conscious act. She is the student who has been promoted the most within the Public Security Bureau, while simultaneously being the one demoted the most. She appears to be skilled at paperwork, and while her combat power isn't specifically mentioned, she lives up to the title of Deputy Director with bizarre physical specs—easily swimming 200 laps in a pool or digging 8 meters deep just because she 'did some shoveling'—though she seems to get bored with work easily.
