Quotes

 * (to Akiko Yosano) "I'm keeping count of the times you saved my life. This time makes exactly five. I like this character and its meaning - correct. Everytime you complete a tally, you add one more "correct" thing to the world. This shows how correct you are. Without you, I'd never see my parents and brother back home again. I'm glad you're here for us."
