Description
Lulu is a mysterious girl who first appears as an infant left on the doorstep of the Kamiyama household. She is discovered by Tenko and Samatarou Kamiyama, who initially mistake her for a stork-delivered child and decide to raise her as their own daughter. Lulu grows at an astonishingly rapid rate, reaching the age of a kindergartner in a single day and continuing to develop far faster than a normal human. Her background is eventually revealed to be extraordinary: she was originally a doll named Lulu owned by a girl named Ai. When Ai lost the doll on an overpass, Lulu was transformed into a human by a divine act, and she returned to the world with the specific purpose of meeting Ai again.

Lulu’s personality evolves in tandem with her accelerated physical development. As a baby, she is content and cheerful, enjoying the attention and care from Tenko and Samatarou. As she grows into a toddler and then a young child, she becomes more expressive, curious, and playful. Her motivations are simple but deeply rooted: she seeks to reconnect with Ai, the person who originally cherished her as a doll. This desire drives much of her later actions in the story.

In terms of role, Lulu functions as a catalyst for character growth among the main cast. Her sudden appearance forces Tenko and Samatarou to step into parental roles, bringing out nurturing and protective sides of both characters. She also serves as a link between the divine and human worlds, as her origin ties directly to Ai, whose own story intersects with the Kamiyama family. Key relationships include her surrogate parents, Tenko and Samatarou, who care for her throughout her swift childhood, and Ai, her true former owner whose memory she carries.

Lulu’s development is marked by her rapid aging and the gradual discovery of her true nature. Initially, she herself is unaware of her origin as a doll, but as she matures, she pieces together her past and embraces her purpose. Her notable ability is this accelerated growth, which sets her apart from ordinary humans and creates a sense of urgency in her search for Ai. She possesses no other supernatural powers, relying instead on her innocent determination and the bonds she forms with those around her.
