Hagoromo's two sons, Ashura and Indra, share a happy childhood, training and playing together. Indra is naturally gifted with great talent, and at a tender age is nicknamed the “genius of Ninshu.” On the other hand, Ashura has no aptitude for Ninshu. Still, the two boys are very close. But Hagoromo is unaware of the malevolent power stirring in the shadows…
In time, I will take over Ninshu
and fulfill my dream.
Schon bald werde ich das Ninshu
übernehmen und meinen Traum erfüllen.
Yo continuaré con el ninshu
y llevaré a cabo este ideal.
Yo continuaré con el ninshu
y llevaré a cabo este ideal.
Continuerò a migliorare il mio ninshu
Com o tempo, eu assumirei o 
Ninshu e realizarei o meu sonho.
