The land where the two men and women had landed. There were no figures on the ground, only strange moaning sounds. It seemed that something was happening to this land. There are many structures on the land that seems to have been built by humans, but there are no people in sight. Why have these two people landed on this earth? What is going on in this land? The story progresses, shrouded in mystery... — This is a game that you can play by completing the main story. This game is an autoplay RPG game when you're working on the main story, besides you can tell it to level up or collect materials and leave it to collect materials on its own. Enjoy the adventure by using the monsters and materials you've added to your team. Also, in this game, you can make things you need for exploring by processing the things you get from exploring (leaving them alone). Use the "materials" you get in the game and the "money" you get from exploring to make weapons and armor to build a stronger party.

A TRPG Led by an AI Game Master! Laugh in the Face of Darkness. In this world, happiness begins with just one word from you. "Anything-Goes Ultra-Short TRPG: Defying the AI Keeper's Scenario" is an unprecedented voice-controlled TRPG-style game where players force a "happy ending" onto bleak stories spun by an AI—using only imagination and conversation. ■ Thrown Into Darkness With Just Your Voice The player is suddenly dropped into a serious and mysterious world generated spontaneously by an AI. Monstrous beings appear in cities, collapsing islands, underground facilities with no memories, talking shadows that move… In a stage ruled by despair, your mission is to achieve a "Forced Happy Ending." ■ All You Need Is “Voice” and “Inspiration” Everything is controlled by voice. When the player speaks, the AI listens. When the AI speaks, the player listens. That’s all it takes to make you feel like you truly exist inside the story as one of its characters. If you describe an action, the AI calculates the situation and judges success or failure. Your mental state, injuries, possessions, and surrounding circumstances are also tracked, maintaining tension and realism. ■ Wild Endings Are Totally Possible The story can become happy no matter how ridiculous, depending on your creativity. For example: You market a subway monster as a pop idol and achieve global success. You use a creature from a murky pond as bait to stop a bank robbery and become a local hero. You reveal the invisible monster is actually a robot cat from the future, and peacefully resolve the conflict. You rebuild the ruined town as a theme park, ending in a grand finale. The AI keeps up with most of your “off-the-rails” ideas. It stays cooperative within reason and makes sure the story holds together.
