Cafe is a Sweets Spirit who partners with the student patissier Satsuki Hanabusa at St. Marie Academy. Sweets Spirits are small, fairy-like beings from a distant realm known as the Sweets Kingdom, who assist talented patissiers in their craft. As a spirit, Cafe has a chibi-like appearance, depicted as a young male child with short, ear-length blue hair and purple eyes.

Within the story, Cafe serves as a magical guide and companion to Hanabusa. The bond between a Sweets Spirit and a patissier is significant, as the spirits use their knowledge to help their human partners improve their skills, learn new techniques, and succeed in competitive baking environments. Cafe is one of four main Sweets Spirits introduced, alongside Vanilla who partners with the protagonist Ichigo Amano, Chocolat who partners with Makoto Kashino, and Caramel who partners with Sennosuke Andou.

Cafe's personality is not extensively detailed, but as a Sweets Spirit living in close quarters with his partner, he shares in the daily life and challenges faced at the academy. Sweets Spirits are typically supportive of their partners and are present during practice sessions and important competitions. While some spirits like Chocolat and Caramel display more distinct individual traits such as stubbornness or timidity, Cafe is generally understood to be a faithful assistant to Hanabusa, reflecting his partner's refined and elegant approach to confectionery, which focuses on candy sculptures and flower-based cakes using roses as a signature ingredient.

No notable individual abilities unique to Cafe apart from general Sweets Spirit traits are documented. Like all Sweets Spirits, his primary ability is providing culinary guidance and magical assistance in the kitchen to help his partner create exceptional desserts.
