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?

Underground? What are you, a mole?
!تحت الأرض؟ أأنتِ خلد؟
Untergrund? Bist du ein Maulwurf?

Subterrâneo? Você é uma toupeira?
Под землю? Ты крот, что ли?
