A conductor-type robot installed in the rear carriage of the interplanetary train AM24, also known as the Milky Subway. It is modeled after an Enhanced Human wearing the female uniform of the Space-武 Railway. Like the train, it was manufactured by Titan Industries. It is generally called "Autumn-chan." The machine connected to its back is labeled O.T.A.M. 800. This translates to "Outer Space Traffic Animatronics Manager." It is connected to the carriage's main computer and equipped with an AI, but it resembles a faded "moving mannequin" where only the neck can move. It is capable of conversation, but it is awkward, and it was reportedly taken out of service due to unpopularity. Being an old unit, it malfunctioned even when Chiharu called out to it (Chiharu thinks it's cute). Machina assumed the main computer was broken, but it misidentified operational keywords from Machina and Chiharu's small talk, causing the train to start on its own. By the way, it doesn't move. Only from the neck up.

The nickname for the security robots inside the carriages. They are mass-produced security robots manufactured by Titan Industries, the same company that made the train. They operate while constantly playing a monotonous tune reminiscent of the "Yobikomi-kun" melody. After waiting for Kanata—who was neutralized first—to recover, Machina and the others were forced to listen to the same music for 50 minutes, nearly driving them insane. First appearing in Episode 5, they likely operate around the 3rd carriage. They deemed Machina's group as targets for exclusion and knocked out Kanata, who entered first, with a taser gun. Later, Machina, Chiharu, and Akane, fed up with the repetitive music, attempted to take it on with a plan. However, because the plan was so poorly executed, everyone except Machina was wiped out. Finally, a desperate Machina paid a reward to hire Kurt and Max, who successfully shut it down.

Enhanced Human / Male / 181cm / A patrol officer at the Ginkyo Prefectural Police Station (Ryoko's junior). An excellent individual who handles work efficiently. A modern, cool young subordinate who leaves on time and doesn't attend drinking parties. He is not intimidated by his senior (and former delinquent) Ryoko and speaks his mind without hesitation. Despite his dry personality, he has a solid, sturdy build, looking every bit the athletic Enhanced Human. However, he is sometimes moved by Ryoko's compassion and her efforts to help prisoners remotely.
