When they learn the truth about the current situation, the gang realize that they must go into battle. And so, too, does Kagura.
You have to grow stronger than me
using the sword of a human.
.عليك أن تصبح أقوى منّي باستعمال سيف بشريّ
Tú mismo debes fortalecer
tu espada, una espada humana.
Você tem que ficar mais forte do que eu 
com a sua espada, a espada de um humano.
