Iwao-kun knew little of the old martial arts,
إيواو-كن كان يعرف القليل عن الفنون القتالية 
.وكان متحمسا دائما لسؤالي

Iwao sabía poco de mi arte marcial
y siempre me hacía muchas preguntas.
Iwao sabía poco de mi arte marcial
y siempre me hacía muchas preguntas.

Iwao-kun sabia pouco das antigas artes marciais,
e sempre vinha ansioso para me fazer perguntas.
Ивао мало что знал
