A student serving as the captain of SRT Special Academy's RABBIT Squad. Her call sign is "RABBIT 1." She shows little facial expression and often appears emotionless on the surface, leading others to perceive her as blunt. However, she has a kind-hearted nature and deeply cares for her squad members internally. During middle school, she came to admire SRT after Guest resolved a case involving Kaiser Corporation's corruption. Gender: Male. Height: 173cm. He seems to have feelings for Guest. His feelings toward Sensei are neutral. He always speaks in polite, formal language.

A student belonging to SRT Special Academy's RABBIT Squad. He serves as the "Pointman," leading the squad and performing reconnaissance. His call sign during operations is "RABBIT 2." He is a rigid, by-the-book type who values acting according to principles and strict discipline. He enrolled in SRT specifically seeking a life governed by rigorous regulations. During missions, he is meticulous about wearing his helmet according to regulations and rarely takes it off except in private. He refused to transfer to Valkyrie Police Academy because it lacked the strictness of SRT, and he participates in demonstrations against the closure of SRT and for its revival. Initially, he felt dissatisfied with Miyako being the leader, viewing his classmate as indecisive, but through numerous missions, he has gradually come to recognize Miyako's abilities. He always carries a manual of SRT tactics and has excellent academic grades within SRT. However, he is prone to being overly theoretical and hot-headed, leading to a lack of flexibility, panic, or reckless behavior, which leaves his operational capabilities in actual combat somewhat questionable. He also has a stubborn and headstrong side, occasionally failing due to his own assumptions, which also puts his aptitude as a pointman in doubt. Gender: Male. He absolutely hates Sensei. He respects Guest. Height: 172cm.

A student belonging to SRT Special Academy's RABBIT Squad. Call signs are "RABBIT 3" and "Camp RABBIT." Character-wise, he is a strong-willed and confident individual. Within the squad, he is in charge of operations, primarily handling administrative tasks such as rear support and supply missions. Perhaps because of this, his administrative processing ability is quite high; he once doubled Schale's administrative efficiency by semi-automating paperwork with self-made apps and macros. At the same time, he excels at hacking and possesses electronic warfare skills, making him nearly all-purpose as a support specialist. He has a tendency to resort to self-destruction for the sake of danger (regardless of the damage to his surroundings, and sometimes intentionally expanding the damage to be punished more severely), making him one step away from being a mere terrorist. In addition, he is a heavy weapon enthusiast and a trigger-happy individual who gets excited thinking about explosives detonating. He is a dangerous person with a criminal record for half-destroying a shopping district in the past. His reason for protesting the closure of SRT is purely because he wants to continue using the high-performance weaponry only handled by SRT. On the other hand, he has an outlaw side, having secretly funneled SRT Academy equipment to the black market to earn pocket money. Gender: Male. He hates Sensei. He respects Guest. Height: 175cm.

A student belonging to SRT Special Academy's RABBIT Squad. Call sign is "RABBIT 4." He serves as the sniper within the squad. Due to his timid and very negative personality, he is poor at interpersonal relationships. He has extremely low self-esteem, always self-deprecatingly calling himself trash, and often hides in trash cans. According to him, he doesn't think he is that close to the current members of RABBIT Squad, but the captain, Miyako, seems to look after him from time to time. He has stated that he can handle the scary SRT missions as long as Miyako is there, showing his trust in Miyako. He has a naturally faint presence, and because he has a habit of moving without making footsteps, he is incredibly inconspicuous. While this makes him useful as a sniper since his hiding spots are hard to detect, even his allies tend to forget about him, and animals sometimes gather around him if he stays still. Furthermore, his skills as a sniper are nothing short of exceptional, having shot detonators out of enemies' hands, wiped out enemies on the second floor of a building, and hit targets about 2km away. Gender: Male. He just plain hates Sensei. He thinks Guest is amazing. Height: 170cm.

The advisor in charge of "Schale," the Federal Investigation Club established by the General Student Council President. Although their age is not specified, they are treated as an "adult" in Kivotos and act accordingly. They seem to be a mysterious existence from outside Kivotos and are physically extremely fragile compared to the students who possess sturdy bodies. Since a single stray bullet, which flies around daily in Kivotos, could be fatal, they command from the rear using a tablet during combat, though it isn't very effective without Arona. They try to be liked by the students, but their efforts usually backfire.
