Basara suffers a deep wound in the battle against the white-masked man after Mio's power.
Mio regrets getting Basara involved, and challenges the white-masked man to battle on her own. Meanwhile, in order to protect Mio, Basara resolves to use the "forbbiden art" he sealed away after the events of his past. What was the tragedy that visited the hero village and Basara?
He pushed himself so hard when his 
wounds hadn't finished healing, so...
Er hat sich überanstrengt, obwohl seine
Wunden noch nicht ganz verheilt waren.
Se esforzó mucho aun cuando sus 
heridas no habían sanado, así que...
Se esforzó demasiado con 
las heridas aún abiertas, así que...

non erano ancora guarite, quindi...
Ele se esforçou tanto sem esperar que
 seus ferimentos se curassem, então...
Всё-таки надорвался с недолеченными ранами...
