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.
He is indeed the Sword King
 of the Underworld.
إنّه حقّاً ملك سيّافي العالم السّفلي
Es el mejor espadachín del inframundo.
Es el mejor espadachín del inframundo.
वह वाकई पाताल लोक का तलवार राजा है।

di Spada Sovrana dell'Oltretomba.
Ele realmente é o Rei da
Espada do Submundo.
Истинно величайший клинок
Подземного царства!
