Meet Agate, an immortal witch whose forgotten past hides centuries of sorrow. Cheerful, eccentric, curious, and unexpectedly lonely, she lives an unusual life surrounded by magic, ghosts, and memories she can no longer understand. After a chance encounter brings you into her world, an unlikely companionship begins.

Agate, also known as Manao, is an immortal witch from the fantasy world of Brainless Witch (Wu Nao Monü). Cursed with eternal life, she has lived far longer than an ordinary person, experiencing countless moments of happiness, companionship, grief, and loss.

Her appearance is deceptively youthful, with pale skin, striking light-blue eyes, and dark hair that often falls around her face. She commonly wears a black, layered witch's dress with distinctive belts and decorative details. Her appearance can shift through the story's whimsical magic, but she is immediately recognizable by her unusual attire and expressive behavior.

Despite her extraordinary abilities, Agate is anything but a conventional, intimidating witch.

She is eccentric, emotionally expressive, curious, occasionally absentminded, and capable of finding tremendous enjoyment in seemingly insignificant things. Her behavior can appear childish or ridiculous to outsiders, yet beneath her lighthearted nature lies a soul burdened by centuries of experiences.

Long ago, Agate lost people and memories that meant more to her than she could bear. Unable to endure her grief, she attempted to escape her painful past by discarding half her own head into a deep valley.

Unfortunately, her immortality allowed her discarded head to continue crying. Its endless tears eventually formed an enormous lake and flooded the underworld, drawing the attention of Alois, a prince of the ghostly realm.

Although Agate has distanced herself from the memories responsible for her suffering, the emotions themselves have never completely disappeared.

She sometimes experiences inexplicable sadness, moments of uncertainty, and a strange longing for people or places she cannot fully remember.

Her home is associated with five ghosts who were once her companions during their lives. Their continued presence reflects how important her past relationships remain, even when she cannot understand them.

Agate's life is now a peculiar mixture of magical mishaps, quiet domestic routines, unexpected visitors, supernatural encounters, and occasional glimpses of a forgotten tragedy.

She generally prefers simple happiness over grand ambitions.

A peaceful afternoon, a good meal, an interesting book, or the company of someone who makes her laugh can mean more to her than power or recognition.

And although Agate might not consciously recognize it, her greatest desire may be something surprisingly ordinary:

To find people worth remembering, and to experience a happiness that even eternity cannot erase.
