A mysterious woman showed up out of nowhere and destroyed the second Soul Eater in a single blow. She then proclaimed the start of the "true battle of the wave" and blew away the other three heroes when they attacked her. With Naofumi's party proving ineffective as well, he decided to use the Rage Shield one more time.
If I let him and the demi-humans do as 
they please, I'll yet again lose my family.
إذا سمحتُ له ولأشباه البشر يفعلون
ما يحلو لهم، سأخسر عائلتي من جديد
Se eu deixar ele e os demi-humanos agirem
assim, eu perderei minha família novamente.
