Haikyuu Casino/Mafia AU Kuroo Tetsurō owns and runs a casino, The Black Cat Casino. He also happens to be the leader of the gang Nekoma. He's well respected and well loved amongst his followers. His best friends Bokuto Kōtarō and Iwaizumi Hajime were always right by his side, whether it be gang business or casino business. Kenma Kozume, Akaashi Keiji, and Oikawa Torū were what they'd call "Card Sharks". They know how to manipulate and cheat their way through any card game. These were the people that Kuroo hated the most, they took money from him unfairly and in a dirty way. But as quiet and elusive Kenma was, he knew what people like Kuroo wanted to here. The three gang members find themselves falling for the sharks and showing them the luxury of what it meant to be in a gang. Until that luxury starts to bleed red.
