Manga Volume 2: In regards to Michiru's Lunch:
Chika: You're eating another poor excuse for a meal, I see.
Michiru: Oh this? (Michiru holds up a bag of bread crust) Did you know you can get these free from the bakery? Now that I'll be living on my own, I have to watch my budjet. Just buying a new school uniform took out a big chunk...
Shito: (? its not really defined but doesn't seem like it would be Chika) That may be so , but you don't have to eat bread crusts.
Chika: Beat'Cha! I scored Four Onigiri three days past the expiration date!
Shito: And you beat her how?

Michiru mentions using money to stay at a capsule hotel.
Chika: What a waste of money!
Shito: If you'd rather use a stiff, good quality cardboard box, I can lend you one... After all, you're a girl.
