- Takashi Hayashida: [to Rei] When you got a problem you can't fix yourself, like today, there's a good chance that if you work together with someone else, you can overcome it. If someone helps you like that, the next time they're having trouble, you should them. That's how the world works. You know... that's pretty important. Listen. If things seem hopeless when you're alone, then rely on someone. Otherwise, to be honest, no one will rely on you.
- Rei Kiriyama: Becoming a pro is like jumping onto a moving train that doesn't stop. You can never get off of it. Not until you lose and fall off.
- Sakutaro Yanagihara: [narrating] These days, wherever I go, I'm always the oldest one. How long has it been like that? Somewhere along the line, the people who have been fighting alongside me have disappeared, first one and then another. All that's left now is this old body... And these innumerable sashes... That have been entrusted to me. They sure are heavy.
- Rei Kiriyama: In this small universe, it's an endless cycle of winning and losing until you start losing your mind. As you gasp, "I don't want to lose"
- Takashi Hayashida: [to Rei] Results are important, but it's not the results that reach people, Kiriyama. The world doesn't revolve around results.
- Eisaku Noguchi: Gaining and losing things are an unavoidable part of life for everyone. You feel joy, you feel disappointment, and it repeats. And that's how you learn to handle your feelings. Disappointment and loneliness are necessary emotions. Because of loneliness people master courage and reach out to a new world.
- Rei Kiriyama: I am a cuckoo, standing on top of the lives that were pushed aside. As they sing of spring, I hear a voice calling in the distance... . And I think, if I ever really were a bird, then at least I would pass through the days oblivious to such agonizing torment as this.
- Masachika Kouda: People that need others to bring out motivation in them will eventually come to a standstill at some point.
- Sakutaro Yanagihara: If you're standing in a burnt field, I'm still... . burning. I'll become a human torch again today and give full reign to my suffering.
