One day over summer break, Goro and the team run into Katsuhiko, twin brother of Yokonan's Yoshihiko. What does his arrival at the school mean for Goro?
Goro-chan! That's the spirit!
Goro-chan, weiter so!
¡Así se hace, Goro!
¡Así se hace, Goro!
Gorô, continue comme ça !
Goro-chan! Continue assim!
Горо! Ты задал настрой!
