The RX-8 is Mazda's proud rotary-engined successor to the third-generation RX-7. The RX-8 is notable for the fact that, despite being a full-fledged sports car with a rotary engine and FR drive, it is a family car with seating for four adults. This was at the request of Ford, Mazda's parent company at the time of its launch, as it was considered an absolutely essential condition for the development of a new rotary engine-powered car in terms of marketing strategy, as it was a four-seater that could be sold in large numbers. In order to meet the conflicting requirements of a family car while delivering full-fledged sports car performance, Mazda adopted a unique mechanism called the 'Freestyle Door', which allows the front and rear doors to open in a double-swinging motion. Within these difficult constraints, Mazda's engineering team succeeded in giving the RX-8 the very best qualities of a sports car. The 13B engine used in the RX-7 had been replaced by a turbocharger, and the RX-8's NA design and numerous improvements resulted in higher revs and lower fuel consumption, while at the same time making the engine lighter and more compact, which greatly benefited the car's turning ability and lower centre of gravity. Mazda named the next-generation rotary engine with these improvements the 13B-RENESISE. Although the 13B-RENESISE engine had less power than the turbocharged 13B engine in the RX-7, it successfully improved environmental performance and fuel economy, which had long been regarded as the weak points of the rotary engine. This complete improvement of the engine was also an essential measure to make vehicles with rotary engines compliant with the increasingly strict emission regulations of countries all over the world. 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 were regarded as the best of any Japanese car, and Mazda's engineers succeeded in achieving the seemingly impossible goal of creating a car that was both a family car and a serious sports car. In 2008 and 2010, the racing version introduced by Mazda USA won its class at the Daytona 24 Hours in the USA, beating racing machines developed by Ferrari, Porsche and others.

Pretty Cure All Stars is the term used by the official side, and is a generic term for the Pretty Cure girls beyond the confines of the work. Several of the toys in the Pretty Cure series are made under the brand "Pretty Cure All Stars" rather than the title of the work. As of March 2016, 44 characters have been promoted under the brand "Pretty Cure All Stars" (43 characters from the TV series plus Cure Echo, who appeared in the film version only). Not all characters who are considered Precure in the work can be included in the "Precure All Stars" framework.E66:E68 It is customary that Precures who are guest characters in a single episode or are deceased cannot be included in the All-Stars. Conversely, characters who were not considered Precure in the TV series are sometimes included in the framework of Precure All Stars. As a result, fans often treat characters who are placed in the All Stars framework as 'regular' Precure. Of course, even among those involved in the production, there is some sway in this counting system, for example, in the film Pretty Cure Dream Stars! In response to the announcement, Yoko Honna, who plays 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 "51 including Cure Mohurun" in his comments at the production announcement.
