I was skimming through my copy of the Azumanga Daioh omnibus just now and I noticed something. In just about every one of Chiyo's speech bubbles, the text is formatted in a different font. At first, it's the same font as everyone else's speech bubbles, but after the "special" where the girls find the abandoned kitty, the font that Chiyo's speech bubbles are formatted in looks more intense than the others. Does anyone know why this is?
