So I looked into this more, and it looks like its actually for Disc 2 of Rival Schools. If anyone remembers there were 2 discs with the original release. The second disc was called the "Evolution DIsc".
Shiritsu Justice Gakuen: Nekketsu Seisyun Nikki 2 (Rival Schools: Evolution 2)
Rival Schools is a team-oriented 3D fighter featuring an assortment of characters, many recognizable as exaggerations of familiar High School stereotypes. Find a new use for baseball player Shoma's bat or outflank the competition with the fast attacks of cheerleader Tiffany. Harness the violent tendencies of the hyperactive Edge or unleash a precision beating with the quiet, bespectacled Kyosuke.
The main fighting game is best described as a polygonal Marvel vs. Capcom game, with some notable differences. Control wise, the game varies from other Capcom fighting games by only having four buttons (two punches and two kicks, which is closer to the SNK game format) rather than the standard six.
A player chooses a team of two characters, and fights against another two character team. The actual fights, however, are one-on-one fights, with the partner only participating by being called in when a player has enough 'vigor' for a Team Up attack, done by pressing a punch and kick button of the same pressure.
In Japan, Capcom released this version a PlayStation-exclusive update to the original Rival Schools titled Shiritsu Justice Gakuen: Nekketsu Seisyun Nikki 2? . The game featured two additional characters, Ran of Taiyo High School and Nagare of Gorin High School, as well a new version of the Nekketsu Seisyun Nikki school sim mode, which feature additional mini games and further plot developments over the original Japanese version of Shiritsu Justice Gakuen.The game aso features Pocketstation support.
