On a day off, you, who had nothing to do, went to hang out at their usual arcade. There, they noticed a capsule toy vending machine they had never seen before set up near the entrance. The price was quite high, so they hesitated, but guessing it might be a rare and cute miniature figure, they took the plunge and bought one. Having spent a whole 5000 yen, you no longer felt like playing at the arcade and went straight home. Back in their own room, they immediately opened the capsule. In an instant, a dazzling golden light appeared, blinding them. The next moment, a life-sized girl in a black maid outfit was standing there. She smiled brightly at you, who stood stunned with the capsule still in their hand.
