Mazda's proud rotary engine vehicle, the de facto successor to the 3rd generation RX-7. The RX-8 is notable in that it is a full-fledged sports car with a rotary engine and FR drive, yet it is a family car that can seat four adults properly. This was at the request of Ford, Mazda's parent company at the time of the sale. The marketing strategy is to have a four-seater that can be expected to sell in volume. This is because it was considered an absolutely essential condition for the development of new vehicles with rotary engines. In order to meet the conflicting requirements of a family car while achieving the performance of a full-fledged sports car, Mazda decided to adopt a unique mechanism called "Freestyle Doors," which allows the front and rear doors to open in a double-sided manner. And within these difficult constraints, Mazda's engineering team succeeded in giving the RX-8 very good qualities as a sports car. The turbocharger was eliminated from the 13B engine used in the RX-7, and the engine was converted to NA with numerous modifications to achieve higher rpm and lower fuel consumption. At the same time, the engine was made lighter and more compact, which greatly benefited the machine's turning ability and lower center of gravity. Mazda named the next-generation rotary engine with these improvements the 13B-RENESISE. 13B-RENESISE had less power than the turbocharged 13B engine in the RX-7, but it also improved on the environmental performance and fuel economy that had long been considered the weak points of the rotary engine. The complete improvement of the engine was also an indispensable measure to make vehicles with rotary engines comply with exhaust gas regulations around the world, which were becoming stricter every year. In 2003, the RX-8 made its debut. In 2004, the year after its debut, the RX-8 achieved annual sales of approximately 60,000 units, an unprecedented sales record for a sports car. However, it was not only in terms of sales and marketing that the RX-8 excelled. The RX-8's braking and cornering performance is regarded as the best among Japanese cars. The idea is to complete a car that is both a family car and a full-fledged sport car. Mazda's engineers have successfully achieved a seemingly impossible goal. In 2008 and 2010, the racing version introduced by Mazda USA won its class at the Daytona 24 Hours in the United States, beating out racing machines developed by Ferrari and Porsche.

Pretty Cure All Stars is the term used by the official side, and is a generic term for the Pretty Cure girls that transcends the boundaries of the work. Several of the toys in the Pretty Cure series are branded "Pretty Cure All Stars" rather than the title of the work. As of March 2016, 44 characters have been promoted under the "Pretty Cure All Stars" brand (43 characters who appeared in the TV series plus Cure Echo, who appeared only in the movie version). Not all characters who are considered Precure in the works can be included in the "Precure All Stars" framework. It is customary for guest characters from a single episode or deceased characters not to be included in the All-Stars group. Conversely, characters who were not considered Precure in the TV series are sometimes included in the framework of Precure All Stars. For this reason, fans often treat characters who are placed in the All-Stars framework as "regular" Precure. Of course, even among those involved in the production of the film, there is some wavering in this counting system, for example, in the case of "Pretty Cure Dream Stars the Movie! For example, upon the announcement, Yoko Honna, who plays the role of Cure Black, stated on Twitter that "there are various ways to count, but there are 50 including Cure Echo," while producer Ten Washio, the creator of the series, stated in a comment at the production announcement that "there are 51 including Cure Mohurun.
