Ouken's past is revealed as his desire to become stronger and put an end to his father's cruel reign is recounted. Over the course of the hard-fought war against the Gigantes, the prince distinguishes himself by his conduct, until one fateful day.
And Fren, you make sure to 
look after Ouken, okay?
ويا فرين، احرص على الاعتناء بأوكين، اتّفقنا؟
Fren, passt auf Ouken auf.
Cuida de Ouken, Furen.
Cuida de Ouken, Furen.
Je compte sur toi
pour veiller sur mon frère.
और फ्रेन, आप ओकेन का ध्यान देना।
E tu, Fren, vedi di badare a lui, d'accordo?
E Fren, cuide bem do Ouken, viu?
Френ, и ты тоже
присматривай за Океном.
