I'm reading the manga for Fate Stay Night, and there's a part on page 15 of chapter 1 where the speech bubbles are handwritten and rather than in the normal manga font. As you can see, this is only for speech, not for the other text boxes, and is only on this page.
Other font styles (like bolded font) are used to indicate things like intense speaking, but it's not clear if this is supposed to indicate something like that. Is it? If not, why is just that dialogue handwritten?
