Questionable translating aside, could you please not typeset using text boxes? It’s poor workmanship to have so many words within a single sentence get broken up between multiple lines and having so many unnecessary hyphens forced in.
Seriously, look at how much free space per text bubble you have to work with. Would it kill your typesetter to not be lazy and shape the text better? It could’ve been three lines, broken up as “It’s quite a // solid defense // network” or four lines, broken up as “It’s quite // a solid // defense // network”. The latter works better because the text would be shaped in an elongated vertical block and match the shape of the text bubble it’s in.
