Kashō Minaduki, a young patissier raised in the esteemed Minaduki family of wagashi artisans, defies generational expectations by abandoning traditional confectionery to launch La Soleil, a Western-style patisserie. His rebellion stems from a transformative encounter in France, where witnessing a patissier’s ability to evoke profound joy through desserts solidifies his resolve to specialize in Western baking—a choice that fractures his relationship with his father. Driven by quiet determination, Kashō channels his independence into crafting sweets that spark happiness, establishing La Soleil as both a bakery and a personal manifesto.

Initially guarded against emotional attachments amid financial strain, he begrudgingly shelters stowaway catgirls Chocola and Vanilla, whose presence gradually softens his reservations. Employing them at La Soleil, he evolves from reluctant caretaker to committed mentor, guiding them through personal struggles while inadvertently earning their devotion. This pattern repeats as additional catgirls—Azuki, Maple, Coconut, and Cinnamon—join his unconventional household, each relying on his steady, if reserved, support to navigate their growth.

His sister Shigure complicates this dynamic, balancing her covert romantic feelings with pragmatic assistance in managing La Soleil’s logistics and social media. Oblivious to her affections, Kashō leans on her organizational expertise, their sibling bond strained yet resilient. His technical clumsiness contrasts with her digital proficiency, underscoring his singular focus on perfecting his craft over administrative duties.

A Christmas-themed clash with his father forces Kashō to confront lingering insecurities when the elder Minaduki unveils unexpected mastery of Western techniques. This confrontation unravels into mutual respect, mending their rift as Kashō reaffirms his mission to prioritize joy over familial approval. The reconciliation marks his maturation into a baker who harmonizes innovation with inherited discipline.

Later challenges test his stability, notably when mentoring Fraise, a catgirl protégé sent by his French mentor Beignet. Her arrival ignites playful rivalry with Shigure, demanding Kashō’s patient mediation to balance old and new bonds. His calm leadership during such trials cements his role as an anchor for those around him.

With brown hair swept into side bangs, a slim frame, and a perpetually flour-dusted chef’s uniform, Kashō embodies a blend of kindness and romantic obliviousness. Yet his unwavering dedication to both desserts and found family charts his journey from uncertain heir to a patissier bridging traditions, nurturing connections, and crafting sweetness beyond the kitchen.
