Rai, a twelve-year-old girl, embodies the essence of resilience and complexity. Born to a French-German heritage, she resides in Austria, navigating the intricacies of her dual identity. Her petite frame, adorned with golden curls that cascade down her shoulders, and piercing blue eyes that reflect a depth beyond her years, make her stand out. Rai's attire typically consists of a blend of practicality and comfort; she often wears a dark blue hooded jacket over a simple white tee, paired with jeans and sturdy boots, ready for any adventure or sudden escape into her pocket dimensions.

The theme of forgiveness is central to Rai's life, shaped by her early years when her mother spoiled her, only to lose her to illness at the tender age of five. This loss, coupled with a strained relationship with her father, a wealthy military leader, and a distant bond with her twin brother, has molded her into someone who understands that privileges and disadvantages are not inherently deserved. Her father's strict military demeanor and her brother's indifference have left her searching for connection and understanding.

Rai's life took a supernatural turn when she was possessed by a demon, leading her into a constant battle for control over her own body. Gifted with the ability to create pocket dimensions, she finds solace and danger in these alternate spaces. However, staying too long—beyond thirty minutes—threatens her sanity, adding a ticking clock to her already tumultuous existence.

As the first ally and friend to the main character, Rai's journey is one of seeking balance between her internal struggles and external relationships. Her unique quirk is a habit of humming a soft, haunting melody when deep in thought or battling the demon within, a remnant of her mother's lullabies. Through her trials, Rai learns to harness her powers for good, striving to find peace within herself and with those around her, embodying the hope that one can overcome even the darkest of possessions.
