While you are in Maihama,
Würden Sie ihm während Ihrer Zeit
in Maihama einige Dinge beibringen,
¿Puede enseñarle lo que nosotros no 
podemos mientras estén en Maihama?
Accepteriez-vous de lui enseigner
ce que nous ne pouvons lui apporter,
Fintanto che ti trovi a Maihama,
Você poderá ensinar a ele
 o que nós não podemos,
Пока вы в Майхаме,
не могли бы вы научить его тому,
