Katakuri: I understand better than anyone how weak I am compared to him. I can't stop him, but I have no choice. This isn't about whether I can win. I have to stand in his way. Mother's Hunger Pangs have started. If even I run away, who will protect my family?!

Bullet: Boros, because it's you, I'm willing to give it everything I've got. I'll be the one to defeat you!!
