Sweets Syūei is a Cake Shop ran by Amanashi Takeshi, a member of the Shūeigumi. Raku Ichijō had helped Amanashi to become a great baker and had finally been able to open up his store. Raku also works at the store part-time.
Most of the shop's sales went up high thanks to Raku's excellent baking skills.
However, due to being successful, the Onodera Japanese Sweets Confections and them have a rivalry, which causes Nanako Onodera frustration towards Raku.
