Tonegawa attends a class reunion where he hopes to see what's become of the classmates he always held in contempt. Meanwhile, Ootsuki's latest excursion is threatened when he gets unexpectedly sick.
We now take wing, our youthful hearts abeat
نحلّق الآن بنبض قلوبنا اليافعة
Wir breiten die Flügel aus,
sie schlagen wie unsere jungen Herzen!
Nuestros jóvenes corazones
emprenden vuelo.
Nuestros jóvenes corazones
emprenden el vuelo.
Prends donc ton envol
Ora prendiamo il volo,
con i nostri cuori di adolescenti che battono forte
Nossas emoções palpitantes abrem asas
Наши юные души расправляют 
крылья и взлетают ввысь,
