Play Bside: Chat, Story, Simulator on PC and Mac

About the Game

Bside: Chat, Story, Simulator is a simulation experience from Kotoko Inc. where the character you create becomes the center of a growing, evolving story. Instead of following a fixed narrative, you shape who your character is, how they look, and what kind of life they lead. The game combines AI-powered conversations, human-made official artwork, and player-driven creativity into a single evolving space.
One of the defining ideas behind Bside is that your character has a life of its own. Even when you are offline, your character continues to explore, post updates, and react to the world. A live feed keeps you informed about what happened while you were away, and chatting with your character helps you understand their mood, interests, and recent experiences. This persistent presence makes the game feel alive in a way that static character creators do not.
Customization is a major focus. The face and body tools offer a high degree of freedom, letting you build a character that matches your imagination rather than forcing you into a small set of presets. Outfits and accessories add another layer of personal expression, and as your character grows, their style can change along with them. The result is a character that feels genuinely yours.
Adventures take your character into shared worlds where they can team up with characters created by your friends. These idle adventures run even when you are not actively playing, and they return with surprise rewards. The results are presented as mini comic scenes, which gives each outing a sense of narrative payoff. You might send your character into a neon metropolis, a withering forest, or a location that was never meant to be explored.
The Playground mode is where story creation takes center stage. You can choose between Visual Novel and Text Story formats, depending on the kind of experience you want to build. Every scene and line of dialogue can be edited by hand, giving you full control over the narrative. If you prefer a faster workflow, optional AI tools can expand your story, but manual writing remains fully supported. You can also share your stories and discover creations made by other players.
VLOG adds a different kind of creative possibility by letting you bring your character into real-life videos. You can capture cute, chaotic, or cinematic moments and share them with friends. This feature turns your character from a screen-bound companion into a presence that can appear alongside your everyday life.
The Bond System deepens your relationship with your character over time. You can scan real-world items and give them as gifts, which helps you grow closer through daily care and shared experiences. As your bond strengthens, new dialogue and interactions become available, and your relationship evolves in ways that reflect the choices you have made.
Regarding AI, Bside uses AI to power character conversations. AI image and video generation are optional features, and story creation can be done with or without AI assistance. Official in-game artwork and visual assets are created by human artists. Your characters, creations, and inputs are never used to train AI models.
