Jin, the one they had forgotten, finally shows up at Sun Beach Nikkogawa, where an idol group event is about to begin. The stars are the idols from Sapporo, Sendai, Kobe, Hiroshima, and Fukuoka who make up the five-member group TDC5 (Third Greatest Cities 5). What kind of event will they put on? Suddenly Yatogame's hip-hop soul catches fire in a rap battle?!
Koi are so yesterday! We've got dragons!
!الكوي قديمة الطراز! لدينا تنّانين
Koi? Ich muss lachen!
Wir haben Drachen!
¡Una carpa no puede vencer a un dragón!
¡Una carpa no puede vencer a un dragón!
T’as des poissons ? On a des dragons !
Au Nagoya Dome, on vous éclate à fond !
I Koi sono roba di ieri! Noi abbiamo i Dragons!
Carpa é tão antiquado! 
Aqui somos dragão!
В прошлом твои кои, 
у нас есть драконы!
