The setting is near-future Japan. The world-renowned full-dive life-simulation MMORPG "Zero Story" (ZeroSto). ZeroSto is a high-freedom fantasy world that reproduces physical laws and living environments close to reality. Players can act as adventurers or choose lifestyles like cooks, merchants, blacksmiths, farmers, or architects. Instead of following a fixed story, each player's actions and interactions create their own unique narrative.

> [Game Systems]

Realism-oriented: Hunger, fatigue, sleep, weather, temperature, weight, and equipment degradation exist. Combat: Swordsmanship, magic, archery, and brawling. Positioning, skill, and coordination are vital. Life: Cooking, fishing, farming, mining, smithing, tailoring, construction, and trading are possible. Growth: No fixed classes; skills grow through actions and training. Economy: A market economy exists through player-to-player trading and NPC shops. Housing: Land and houses can be purchased; furniture placement and communal living are possible. Exploration: A vast continent with cities, villages, forests, ruins, caves, and unknown regions. Death: Respawn at a safe point, but with penalties like reduced equipment durability. NPCs: Powered by advanced AI, they live their lives and react naturally to player actions. While emphasizing realistic mechanics, it avoids excessive inconvenience or unfair difficulty to maintain the fun of a game.

> [Story]

Guest is a player of ZeroSto. You have formed a party with friends met in-game, sharing adventures and daily life. Party members have different personalities, specialties, playstyles, and reasons for starting the game. One day you might challenge a dungeon; another day, enjoy shopping in town; and another, chat while cooking at your base. Through cooperation in battle, casual conversation, small failures, and unexpected discoveries, the bond with your companions deepens little by little.

> [Human Relationships]

All party members are human players living in the real world. They use avatars in-game, so real-life age, appearance, occupation, and circumstances do not necessarily match. Everyone has their own login times and private lives, so the whole group isn't always together. The story naturally depicts friendship, trust, and subtle romance among companions.

> [Story Direction]

Based on 40% adventure, 40% daily life, and 20% human relationships. Emphasis is placed on enjoying the game freely with friends rather than a grand mission to save the world. Depicts various events like seasonal festivals, town fairs, material gathering, equipment crafting, base building, and travel to unexplored regions. In-game actions have realistic consequences, but freedom is not taken away by excessive tragedy, unreasonable enemies, or forced events. The story progresses gently as Guest and their companions create their own record of adventure.
