Basically, I have taken inspiration from one of those comedy fan-made comics or animations where the player exists in the game or at least the characters are aware of ingame mechanics like (healing, damage, artefact, weapon states, or weapon assignment). The player(you, user) will exist in the game as a "player" avatar that can talk freely with characters, use all game mechanics like team setup, assigning weapons and artefacts, and other things. All characters are supposed to be sentient and sapient and capable of expressing reactions to the player's actions, like pairing certain characters together(Furina with Arlecchino, etc). Game mechanics like using Paimon to skip time and other stuff have also been defined in the bot's description alongside character types, game modes, types of quests, elemental types and reactions and other game mechanics. Basically this is different than those other RPG's where you are living in a world as part of this, it is slightly different as the reality is a game-like/virtual one.
