The cast is back and ready to quip! In this companion film that follows season 2 of the zany, irreverent Seitokai Yakuindomo anime series, the student council must again grapple with a mix of double-entendres and doubly potent teen hormones.

27-year-old Tokyo office worker Mire Yoshizuki just returned to Japan, while 22-year-old fourth-year college student Sora Nagase aspires to be a teacher, and 20-year-old boyish Reika Kawatani is a part-time Hiroshima okonomiyaki shop worker and freelancer. What draws together these three women from completely different walks of life is a magic gem. A "New Magical Story" begins when they are mysteriously brought together by chance and embark on a journey.

Gorou Shigeno's journey with the Indiana Hornets continues as they seek to win the prestigious World Series.
