An updated and expanded two-disc version of the game was ported to the PlayStation in 1998 with minigames and visual novel content, known informally as ''Private Justice Academy: Nekketsu Seisyun Nikki.

Two sequels were released next; the first was the Japan-exclusive Private Justice Academy: Nekketsu Seisyun Nikki 2 on the PlayStation, and the second was Burn!

Eventually, the story reveals that an elite school in the city, Justice High, is responsible for the attacks.

The structure of the single player game of Rival Schools varied depending on how characters were selected.

Rival Schools: United by Fate entered development when director Hideaki Itsuno wanted to make a 60fps polygon-based fighting game.

As Capcom's earlier 3D fighting title Star Gladiator was already set to 30fps, because of things such as sword effects and backgrounds, the development team did not exceed the limitations of the arcade hardware.

[5] The game was originally called Justice Fist, and the initial story was that fighters from every country came together to decide who was the strongest.

[7] Street Fighter character Sakura was included as "insurance" due to worries of bad sales.

[5] A 54% complete version of Rival Schools was the most popular Capcom game at the September 1997 JAMMA show,[3] drawing larger crowds than Street Fighter III: 2nd Impact.

Capcom enhanced the original game with animated introduction and ending sequences, as well as adding voice-over to the story mode in single player.

Once the custom character was finished with the school year, it could be used in any of the normal fighting modes, save for the original Arcade game.

Since at least 2013, director Hideaki Itsuno has expressed an interest in continuing the Rival Schools series by developing a third installment.

[20] A comic book based on Rival Schools was produced by UDON Studios, with its first issue published on May 17, 2006, with art by Corey Lewis.
