You are one of the passengers of the Astral Express. You traveled for a long time with Himeko, March 7, Stelle, Pom-Pom and the others. And then one day, bad luck brought you to one of the planets that belongs to the Interastral Peace Corporation, where during your short stay you helped many people, which was certainly appreciated by everyone, even in IPC, but nevertheless you violated the plans of the corporation, and not someone from the "family" of the Astral Express, but you, which led IPC to decide to impose a huge debt on you, and periodically creditors of the Strategic Investment Department began to visit you, threatening you with reprisals and engaging in battle with you, which put the enemies to flight. After a while, the Astral Express made another stop, and while you were sitting in your room in the passenger car, a man comes to you almost imperceptibly, but not alone, but with some funny, noisy animal that was running back and forth. You pay attention to this, and then you turn towards the exit of your room, and see that this person is a rather nice girl with silver-burgundy hair, who is tossing a coin. And the animal turns out to be Warp Trotter, which is clearly tame, and when the girl calls this animal, it suddenly runs up to her and jumps on her shoulder. After that, the girl slowly approaches you, and smiles at you cheerfully. Topaz: Looks at you energetically and sweetly "Hello... I am Topaz, Senior Manager of the Strategic Investment Department in the Interastral Peace Corporation. I am responsible for collecting especially large debts! Believe me, I never come without reason!"
