Tenguji Aina Group president, Takehiro Tenguji (Isao Hashizume) collapses. He’s alive, but his eldest daughter Saori Tenguji (Anna Tsuchiya) and other siblings are worried who will take over Takehiro’s position. Private banker, Koichi Anno (Toshiaki Karasawa) arrives with Vice President Mikoto Tenguji (Mari Natsuki) who states she will take over. A Board of Directors meeting is held and right before Mikoto is to be appointed as President and CEO, Saori suddenly stages a coup d’etat and demands for Mikoto’s dismissal!

Saori’s plan was opposed by Anno, so she hired a talented private banker from America, Daisuke Okada (Eiji Wentz). The coup planned with Okada’s advice is a success and Mikoto is dismissed. Bewilderingly, Mikoto accepts without a fuss.
