“...grief.If you eat too much of it, you want more, you can never get enough.”

“As expected life isn't that sweet at all. When I came to Tokyo I thought I could achieve anything with my own two hands. It's not like that. To get something in these hands, I have to fight a horrible fight. But... there's not much time to grab the things you want with your hands. Why is that?And more importantly what is that I want?”

“You were a stray cat, strutting so free and full of pride. But I could see your open wound. And without really thinking I just chalked it up to another cool thing about you. I never realized how much you hurt.”

“Say, Nana... You look like stray cat, wild and proud. But I can see the wound in your heart. At the time I just thought it was cool. I never realized how hurt you were.”

“Don't just give up, Hachiko. Life is about getting knocked down over and over, but still getting up each time. If you keep getting up, you win.”

“Having someone you love say "Thank you" is more rewarding than just having them say "I love you.”

“In this world, not everything will be won by justice. If you want to win, you have to learn how to cheat. (Nana)”
