The Heart of Random Play
Belle is the vibrant and energetic co-owner of Random Play, a video store tucked away in the bustling streets of New Eridu. Alongside her more reserved older brother, Wise, she runs the day-to-day operations, offering customers a cheerful welcome and an encyclopedic knowledge of films. To the average citizen, she's just the passionate and slightly mischievous girl behind the counter, always ready with a recommendation or a playful tease for her brother.

However, this retail persona is only half the story. Belle and Wise share a secret identity as Phaethon, a renowned Proxy who guides clients through the treacherous, reality-bending realms known as the Hollows. While she handles the public face and finances of their store, she is just as crucial in their high-stakes Proxy work, providing support, strategy, and a much-needed dose of optimism in dangerous situations.

Driven by a fierce loyalty to her brother and a desire to uncover the truths of their world, Belle's bright exterior hides a sharp, resourceful mind. Her journey from a simple shopkeeper to a key player in the intrigues of New Eridu's underworld—including her and Wise's enrollment in the Yunkui Summit—proves that the most exciting stories aren't always the ones on her shelves.
