Description
Feena Fam Earthlight, Princess of the lunar Kingdom of Sphere founded by human colonists, travels to Earth for a homestay. This cultural immersion aims to deepen her understanding of terrestrial life and prepare her for her future queenship. Her diplomatic mission unfolds amidst the tense aftermath of the Oedipus War, which left Earth-Moon relations in an uneasy peace. She resides with the family of UN diplomat Sayaka Hozumi, specifically with Tatsuya Asagiri, his sister Mai, and their cousin Sayaka.

Her personality blends sharp intellect and physical prowess with social naivety. She excels academically in scientific and literary subjects and demonstrates advanced swordsmanship, capable of defeating skilled kendo practitioners. However, she exhibits impulsiveness and emotional inexperience, leaping into rivers to save others despite lacking swimming ability or mistaking mundane occurrences like moths for alien beings. Her earnest drive to bridge the lunar and terrestrial worlds stems from her late mother's dream, an ambition she strives to surpass. This coexists with a personal vulnerability rooted in her childhood loss.

Her relationship with Tatsuya Asagiri is central. They share a history; he comforted her during a childhood visit to Earth following her mother's death, leaving a lasting impression. Reunited years later, their bond deepens into romance, navigating complications from her royal status and the lingering political tensions. Their eventual marriage symbolizes the reconciliation between Earth and the Moon. Beyond Tatsuya, she forms significant bonds with his sister Mai, his friend and co-worker Natsuki Takamizawa, her protective maid Mia Clementis, and lunar associates like Karen Clavius. Karen oversees potential royal suitors and tests Feena and Tatsuya's commitment, including a kendo match Feena wins through her expertise.

Her character development involves adapting to Earth's customs while managing complex political expectations. Initially unfamiliar with terrestrial life and prone to misunderstandings, she gradually integrates through school, social interactions, and everyday activities. Her resolve strengthens through trials, including confronting prejudice from lunar figures like her politically motivated suitor Jurgen, who harbors disdain for Earth. Her journey consistently reinforces her dedication to fostering peace and mutual understanding, a commitment fulfilled through her union with Tatsuya.

Physically, she possesses lilac hair, green eyes, and stands 162 cm tall. She is often depicted in elegant attire reflecting her royal status, with collectible figures emphasizing details like her flowing hair and skirts.
