The Divine Fist of the North 
Star doesn't come cheap.
وقبضة نجوم الشمال القدسيّة لا تأتي بالرخيص
Und diese Faust

Y el Puño Divino de 
la Estrella del Norte no es barato.
Y el Puño Divino 
de la Estrella del Norte no es barato.
L’art divin de la Grande Ourse,
c’est du sérieux.
E la Divina Arte di Hokuto non è a buon mercato.
E o Punho Divino não é barato, não!
