The wait is almost over.

On March 31 at 12:00 AM (PT), Bside officially opens its doors — and with it, a brand new kind of world where your OC stops being a concept - and starts living.
Bside is more than a dress-up game, more than a roleplay space, and more than a simulation.
It’s a living, online universe where your Original Character (OC) becomes something real - something that evolves, reacts, and grows alongside you.
You don't just create a character here. You shape an identity.
From their appearance to their story, every choice you make defines who they are - and who they might become.
We're launching with a world that's bigger, more expressive, and filled with new ways to play, create, and explore.
Whether you want to recreate an existing OC or build something entirely new, Bside gives you the tools to bring them to life.
Your OC doesn't stand still.
They explore worlds, react to events, and develop their own presence over time. Through a dynamic system supported by AI, your character’s behavior and experiences are shaped by the backstory and choices you give them.
It’s not about controlling every step - it’s about watching who they become.
Step into different worlds - from neon cities to mysterious forests - and send your OC on adventures.
Go solo or team up with others. Discover hidden stories, collect rewards, and bring back moments captured as stylized scenes.
Every journey adds another layer to your character’s life.
For the first time, you can create your own stories.
With Playground, you’re not just playing - you’re building.Design scenarios, craft narratives, and let other players bring their OCs into your world.
Your imagination becomes part of the universe.
Unlock new outfits, collect rare pieces, and style your OC your way.
From everyday looks to statement designs, the Gacha system adds surprise, excitement, and endless possibilities to your wardrobe.
We believe characters should feel personal - not static.
In Bside, AI is used as a supporting system to help your character remember, react, and grow based on the identity you create. It powers personalized interactions and evolving experiences, while the core UI and assets remain human-made.
Your character is still yours — always. We do not use player data, character content, or conversations to train AI models, now or in the future.
To celebrate launch, we’re kicking things off with a 7-day login event:
Just show up - we’ll take care of the rest.
