OVA
Description
Vanilla is a white-furred catgirl with blue eyes, known for her reserved demeanor and subtle expressions. She has white hair with a pink undertone styled in twin tails secured by blue ribbons. Her typical attire is a light blue and navy lolita-style dress, white socks, and blue Mary Jane shoes. A gold bell adorns her collar ribbon after she completes her independent catgirl training.

Vanilla and her twin sister Chocola were abandoned as kittens with no memory of their original owners. Kashou Minaduki and his sister Shigure discovered them critically ill from malnourishment and cold, nursed them back to health, and brought them into the Minaduki household. They initially struggled to adapt, drinking only water and avoiding food during their recovery.

Six months before the main series, in the prequel *Koneko no Hi no Yakusoku*, Vanilla and Chocola appear as timid newcomers adjusting to life with the Minadukis. They gradually learn to trust Kashou, calling him "master," and experience their first Christmas with the family. This period highlights their hesitance and foundational bond formation.

Vanilla possesses a stoic, quiet personality that often masks her emotions, contrasting with Chocola's energy. Despite her reserved exterior, she demonstrates sharp intelligence and pragmatic insight, frequently offering astute observations. Her deep loyalty to Chocola defines her actions; she follows her sister unconditionally, even stowing away in Kashou's belongings when he leaves to open his patisserie, La Soleil. After convincing Kashou to let them stay, Vanilla assists in the bakery alongside Chocola.

Her development includes undertaking the "Bell" program for independence. During training, she studies etiquette under Cinnamon, though the lessons devolve into comedic distractions. Vanilla later experiences her first heat cycle, initially concealing it before acknowledging her feelings for Kashou. This leads to physical intimacy to relieve her condition, deepening her emotional connection to him while she maintains her typically composed demeanor.

Vanilla's relationship with Kashou evolves into mutual reliance; she supports his baking at La Soleil and shares personal moments, like a group amusement park visit where she quietly enjoys the festivities. Underlying affection occasionally surfaces, such as expressing gratitude for outings or showing subtle jealousy toward his interactions with others. Despite growth, she retains core traits like dry wit and a preference for solitude, often seeking quiet spaces. Her central bond with Chocola persists, frequently seen resting or engaging in activities alongside her sister.
