OVA
Description
Princess Chorus ranks among the eight Princesses of Valhalla. Initially presented as enigmatic, she exhibits peculiar behavior and frequently delivers off-topic statements. Her appearance features prominent metallic wings, enhancing a cyborg-like aesthetic. Early encounters involve her claiming robotic nature and announcing imminent power-downs, assertions contradicted when she sneezes after a self-imposed countdown ends. She possesses the capability to sense others' emotional states or "cosmos," visualizing these by generating printed images while holding a printer's power cable. She often makes anime references and offers cryptic prophecies, such as warnings about a three-headed golden dragon or a white comet threatening Earth, though these declarations prove inconsistent and lack follow-through.

A significant personality shift occurs in Season 3. She becomes notably more grounded and less robotic, abandoning her princess attire for ordinary clothing and adopting more typical human behavior. This change coincides with her relocation to live with Princess Laine, though the catalyst remains unspecified. Despite this evolution, her interests persist, including a continued fondness for manga and anime, activities she often shares with Princess Valkyrie.

Her relationships are multifaceted. Upon arrival, she resides temporarily in Rika Tokino's closet, initially unsettling Rika, though their rapport warms gradually. Interactions with Kazuto Tokino involve gratitude for allowing her stay, but no deep connection develops. With Valkyrie, she maintains a positive friendship, evidenced by shared manga reading sessions and Valkyrie's use of the childhood nickname "Chorey." Her bond with Princess Laine is particularly significant, stemming from their school days; Laine, despite past frustrations over Chorus's deceptions, emerges as her closest confidant. Other dynamics include uneasy ties with Princess Hydra, who finds her oddities unsettling, and a neutral association with Miss Sanada, communicated via email during a period when Chorus temporarily ceased speaking.

During later narrative events, specifically the splitting of Valkyrie into separate adult and child entities, Chorus remains present within the ensemble. However, documented individual story arcs or further evolution are absent. Her demonstrated capabilities, such as emotion sensing and technological interfacing, receive no expansion in subsequent official media beyond their initial introduction.
