Yeah I don't think that font is a good idea. In this specific bubble it's not as bad, but on earlier pages you've got those weird parts where an L overlaps with the following letter, it really doesn't do the text's readability any favours.
I get the intent and I'm all for it, but there must be fonts that would get the vibe across and maintain readability.
The intent might have been to convey different tones, but it's used in completely different situations and I have no idea what they were meant to convey
The font just looks uselessly fancy. It doesn't convey bloodlust when Aria used it, nor whatever the scout was feeling while asking if the orcs were really gone on page 11. I was just confused when I saw it honestly. (I even wondered if it was seduction; it might just be the kind of pick-up lines that work on her.)
So definitely not a good idea with the fonts used; it just took me out of it.
As for readability, I didn't even notice the overlapping L; my brain just skipped over it. XD
Maybe use something like the "killer on repeat" font to express bloodlust (I just searched for blood dripping and this one seemed nice enough)?
But personally, I don't think any special fonts are really needed. Mostly, it takes away from how the scene is expressing itself by forcing an interpretation of the tone used. If no special font was used originally, then I don't think the translation should use it either. It was already using black bubbles in this case (which I assume was also in the original) so the change in tone is already conveyed.
