Cornelia: "The body will become weak if all you do is read. You also have to exercise a little."
Mini: "Oh, it's book big sis."
Cornelia: "Ahh! Stay away! I'm not good with fire!"
Mini: "Read me a story, big sis!"
Cornelia: "Nooo! S-stay over there!"
Cornelia: "Oh, Page 17. Could you help me organize some books?"
Annie: "All right... Geez, Page 97 has completely dried out in this book..."
Cornelia: " And Page 211 has shriveled up in this one. The loss of interest in books has become really serious..."
Yoko: "Oh, Miss Page 65537. Have you come across any good books lately?"
Cornelia: "Actually, I just recently acquired 'Mrs. Shirley's Lover.'"
Yoko: "I'm so jealous... So, what do you think of it?"
Cornelia: "Of course, it's.... Fufufuu."
Yoko: "Make sure I get it next. Ufufuu..."
Lily: "I've lived in a remote village for so long that I'm out of touch with current fashion threads..."
Cornelia: "I'm in a similar situation too. I was stuck in a library for so long..."
Lily: "We're pretty similar, fufufuu. Well then, shall we go to buy clothes in the city together?"
Cornelia: "By all mean, let's go together. It's fun to be fashionable every now and then, fufufuu..."
Lily: (I won't lose to some unrefined glasses girls...)
Cornelia: (I don't want to lose to this country bumpking
Cornelia: "Mephisto... You didn't return the book you borrowed from the Monster Lord's Castle, did you?"
Mephisto: "Now that you mention it, I had completely forgotten about it. I'll reprint it, can you wait a little longer?"
Cornelia: "Really... Is that the language of someone in the teaching profession?"
Mephisto: "I take anything I can because it is my doctrine..."
Cornelia: "I see, you're now prohibited from entering the library."
Mephisto: "...There are matters like this too. I'll have to warn the students not to get too greedy."
