Ichigo begins intensive training in order to create her own original Strawberry Tart recipe, but is having trouble with it. When Kashino has a taste, he points out that the problem is with the strawberries and she realizes that she needs special strawberries with a unique taste like the ones her grandmother used. However, the strawberries aren't available anymore, so Ichigo decides to use Heiress's help to look for them. After traveling back to Japan using the Sweets Kingdom toy train, Ichigo samples the Heiress's top-quality strawberries, but still can't find one to suit her tart. She goes back to her grandmother's garden and finds the special patch of soil her grandmother uses. After finding a few of her grandmother's strawberries, Marron tells her that her grandmother's strawberries were called fraises de bois, and the soil that her grandmother used was from the Sweets Kingdom. Ichigo returns home to the Sweets Princes, and later the Chairman calls Kashino to inform them that Team Tennouji lost the semi-finals in the World Cake Grand Prix.
