River City Melee: Battle Royal Special is the latest Kunio-Kun series entry which arrived on PlayStation 4 consoles earlier this year. It's now coming to PC, due this week, on September 14. 

BlazBlue developer Arc System Works marked the announcement by launching a Steam page for the action-adventure-sports 'em up. "This is the most recent installment of the Kunio-Kun franchise, recreated as a fun and easy fighting game with the fighting aspects taken and upgraded from River City Super Sports Challenge: All Star Special," so reads its Steam blurb.
