Yuuy: Because he doesn't yet know that everything is translated in Kiseki, he struggles through writing Japanese. His handwriting is really crappy and full of mistakes... If he were to write in French or Italian, though, his handwriting would improve leaps and bounds. It'd be crisper and clearer to read. Kero: His handwriting is awful. Since it's hard to hold a pencil. Sakura: Very elegant and precise. Fuuma: Horrible, horrible handwriting. Hard to read in places, but he does not give a fuck. Kurogane: He CAN write really elegantly (since idk his bizarro Japan probably had fancy-pants calligraphy and shit). He just hates to do so. And since he only has one arm, holding the journal and writing is really damn hard. So he mostly uses the voice feature when communicating through the journal. Himawari: Her writing's bubbly and girly and cute looking. Kind of overly so, in some ways, just because it's another weird displacement of hers. Hokuto: Big and ridiculous writing, hurray!
