The Gulf Coast Cup (湾岸カップ, Wangan Kappu) is a Keijo tournament held at the Funabashi Keijo Stadium.
Returning from the Butt Island, Nozomi learns that her challenge to Fuyuyu Tsurugi is reported in news, but it's only featured in a very small corner. Sumire tells Nozomi that a top player won't take a statement from a rookie like her so seriously, advising Nozomi to get a promotion. Nozomi then learns that she needs 200 points to advance to the A-Rank. Meanwhile, Sayaka, Ai and Sumire have been confrimed to be able to get their promotion. On the other hand, Nozomi defeats various opponents, but her points are still not enough.
Later, Nozomi gets advised by her fellow Hyougo Branch players to participate in the "Gulf Coast Cup", a tournament held in Funabashi to obtain more points. Although Nozomi experiences trouble as the East players gang up on her, she is able to advance to the finals. There, Nozomi is assisted by her former roommate, Kazane Aoba. Fortunately Nozomi ultimately manages to defeat Rio Kosugi, the most veteran player of the Funabashi Branch, winning the competition.
Accepting her defeat, Rio invites Nozomi to comeback to Funabashi someday. Claiming that, until that time, Rio will do something with her weakness.
