La Soleil is a patisserie shop sporting a western-style flairs and modern outlook on the outside. A localized shop small, but very studious. Its main entrance is a double doorway between large panels of windows. The interior house multiple chairs and tables on the shop floor for eat-in purposes. In the backroom is a large kitchen for baking, containing modern kitchen equipment. There is an apartment at the patisserie's upper level where Kashou, Chocola and Vanilla reside.
The shop is has an active advertising campaign spearheaded by Shigure, and after establishing itself as a business to the area, the shop branches out into running a delivery service.
Later, Shigure and the Minaduki catgirls all become employees of the cake shop against Kashou's judgment. Despite his predicament of having more workload in the bakery, the shop now became a more busier place thanks to the attractive girls working around the shop and accepted the girls working with him nonchalantly.
