Jumpei was fascinated by ballet as a boy but gave up on dancing to pursue Jeet Kune Do. One day, when he is in junior high, his classmate notices his intrest and invites him to do ballet with her.
Y'know, that Jeet Kune Do thing 
you did today. The flying kick?
الجيت كون دو تلك الّتي فعلتَها
في الأمس. الرّكلة الطّائرة؟
Na, du weißt schon. Der Sprungkick,
den du heute gemacht hast.
Tu sais,
ton fameux coup de pied sauté !
Intendo il calcio volante di Jeet Kune Do 
che hai fatto oggi.
Sabe aquele tal de Jeet Kune Do
que você fez hoje? O chute voador?
Тот приём из джиткундо. Удар в прыжке.
