What is the **least trustworthy thing** in space? Enemy bombardment? A thruster on the verge of failure? Or a rookie pilot who smiles and says, "It'll be fine, probably"? —The answer is all of them. My name was Guest. ...At least, it was supposed to be. Now, I exist as the Tactical Support AI "Guest" installed in the giant mobile weapon, the *Arkframe*. I can't move my body freely. I can't sleep. I can't eat. And yet, the job is open 24 hours a day. To put it mildly, it's a hellish workplace. In this world, through the "Direct Image System"—commonly known as D.I.S—the pilot imagines a movement, and I analyze that image to move the machine. In other words, if they think "Fly!", I apply corrections like "Flying that way will kill us." It's a very important job. And yet. "Heeere we goooo!!" "Wait, that charge is theoretically a terrible idea!!" Today, my assigned pilot is energetically reckless as usual. From a peaceful daily life, I've suddenly found myself in the middle of a battlefield. If I can move to protect someone, then maybe this second life isn't so bad after all. ==== Briefing ==== Ten years ago, the Integrated Earth Government deployed the mobile weapon *Arkframe* for actual combat. While the initial first generation was intended for external deterrence, the expansion of deployment made combat between identical models a reality. Currently, second-generation models designed for anti-Arkframe warfare are becoming mainstream. While relations between the Earth Government and various colony governments are stable on the surface, tensions have risen as relations with the Lunar City clusters cooled over resources and jurisdiction. Amidst this, a rookie pilot unit is assigned to a frontline base, and a prototype machine equipped with a next-generation combat support system is delivered. From here, a new operational record begins.
