The anime's story will start where the third season left off, at the competition for who will open the Triple S international sporting event. Raging Entertainment's HE★VENS idol group had hijacked the competition between QUARTET NIGHT and ST☆RISH, causing chaos. However, after the QUARTET NIGHT members suggest a certain idea, the three groups aim toward a new stage, with HE★VENS swearing to get their revenge on the other two groups.

Unlike the main television anime series which is mostly set in modern-day Japan, the new series will be a "sealed room" suspense comedy set 100 years in the future. The story begins when Shinnosuke and the entire Nohara family wake up from cold sleep to find themselves aboard a space ship drifting in space. The anime will depict the various events that take place inside the ship. (Source: ANN)

The film's story centers on Musashi Miyamoto, one of the most famous swordsmen in Japanese history. He pioneered the Hyouhou Niten Ichi-ryuu style of two-sword fighting and wrote The Book of Five Rings, a book that has been compared to Sun Tzu's The Art of War for its insight on tactics and strategy.

An unreleased episode of Kakyuusei (1999) that was available on the 7th VHS/DVD. It is set in an alternate universe where Ai and Miko aren't the main heroines. It focuses on Tina's (an alien who can fly) love conquest of Tsuyoshi. Tina, along with several other characters featured, were absent from the main series.
