The owners of the patisserie are Kazuki and Otoha Hanazuki (Aiko's dad and mom) with Otoha's brothers Olivier, Julien, and François. It has been seen and/or mentioned in every episode, serving as the meeting place for Aiko and her friends, a segway in the plot, as well as a major center for festive. The name is a French word for "Café of Beautiful Days".
Its appearance is beautiful, adorned with a red and gold facade topped with crescent-like finishes, and pink glass door with a sign that says "Bienvenue" (French for 'welcome'). It is also guarded by two stone unicorns, who now and then move and give personal opinions. Not to mention the food as a favorite among the residents, and from the menu, houses a wide assortment of sweet foods, for whom without, the Harajuyork inhabitants head into a sort of path.
The rooms inside the house include a counter where Aiko's family works, six tables each with 5 seats, a dining room, a very large basement and at least two bedrooms. Aiko's room is filled with pink and a bit of pastel colors. This includes bed, studying desk with pink chair, wardrobe, pillow-styled seats with pink table, medium pink bureau, pale pink lamp, heart-styled clock, and posters of Pierre Kox on the wall.
