@kwendy ok listen here, you FAIL completely to understand her role as a character.
That just for showing she a strong will of rightful and justice and not some cry baby. It never mean to be kick-ass. She is mean to be just as weak. but regardless the dangerous save the protagonist many time, and only her can save his soul. Because pure strength alone can't do any of what her did. What make it work because she is just helpless human and how much struggle against all this problem
It also showing in this chapter. She run straight to attack Yato's dad here even there is no logic way she can win. She hear he try to hurt them, that character spirits still right there. Open your eye.
