River City Girls[a] is a 2019 beat 'em up video game developed by WayForward and published by Arc System Works.

A spin-off in the Kunio-kun franchise, the game stars Misako and Kyoko (originally appearing in Nekketsu High School Dodgeball Club: Soccer and Kunio-tachi no Banka respectively) who fight their way through enemies and obstacles to rescue their kidnapped boyfriends, series protagonists Kunio and Riki.

The game was released for the Nintendo Switch, PlayStation 4, Windows, and Xbox One in September 2019, and for Amazon Luna in October 2020.

[2] Shin Nekketsu Kōha: Kunio-tachi no Banka (1994), where Misako and Kyoko previously appeared, was localized by WayForward as a prequel, River City Girls Zero, being released for the Nintendo Switch on February 14, 2022 and September 21 on other platforms.

A sequel, titled River City Girls 2, was released by WayForward and Arc System Works that same year in December for Japan, Asia and the US.

[3] Characters also gain experience points and level-ups from defeating enemies, as in River City Ransom: Underground.

[3] In multiplayer, if only one character is knocked out, it is possible for the other player to revive them by standing over their fallen body and repeatedly kicking their departing soul back into it.

Misako (voiced by Kayli Mills) is in detention at River City High, accompanied by her best friend Kyoko (Kira Buckland).

She receives an alarming message on her phone: a picture of Kunio (Greg Chun) and Riki (Kaiji Tang), the heroes of River City High and their boyfriends, seemingly being kidnapped.

Tierney approached Rudis with the idea to co-direct a new entry in the Kunio-kun series and take the game in a new "goofy, zany direction".

[3] A director at WayForward introduced Tierney to Shin Nekketsu Kōha: Kunio-tachi no Banka, during development and he instantly loved both Kyōko and Misako, the two playable female characters in the game.

[8] During development, Tierney learned from Arc System Works that Kyōko and Misako were no longer acting as the girlfriends for the main protagonists of the franchise, Kunio and Riki.

[9] Priscilla "Rem" Hamby, the illustrator of the webcomic Devil's Candy, was sought out to re-imagine the Kunio-kun characters.

River City Girls was released in September 2019, generally over digital distribution channels such as the Nintendo eShop, PlayStation Network (PSN), Xbox Games Store, Steam, and GOG.com.

[28] Some of the more ambivalent reviewers felt that the beat 'em up action was ultimately a tad repetitive, while others pointed out that the RPG elements such as equipping accessories were often so minor as to be ignorable.
