“Nobody can know ... just how heavy a burden trying to protect another human being can be. I was still a child. I couldn't have understood the real meaning of my promise.”

“If I can protect, I want to protect.”

“Just because you know it [my past]... doesn't mean that my wounds are a weight you have to carry. ~Kurogane-san”

“Kurogane: For all my life... I've wanted strength. I didn't want those things precious to me to be taken away from me anymore. But, to have strength means to invite disaster to come to you. And strength alone can't really protect you.”

“If you don't want her to go, you should say it. Those jerks who can't say a word no matter how much time passes ... I just don't get them. If they're doing whatever the hell they want ... then you should do what you want too. I hate those jerks who fool themselves into thinking that just because they clam up, nobody knows what's going on with them!!”

“Kurogane: You just said "Buu" with your mouth, right? That isn't whistling.Fai: I don't know how to whistle.”

“The guy who isn't in the know can't understand ... how hard it is to be in the know and still not say.”
