@SomewhatOkay Thank you for the translation. The text extending outside the speech bubble is indeed a handy tool to use. But if I may suggest something, instead of whiting out the background of the text manually(it looks like?), it would look cleaner and be easier to create a white outline around the text.
If you're using photoshop:
you type out your text layer > click the small
fx button at the bottom of the bar > Stroke... > Set size for 3-4 px > Color: White > OK
--And there should be a white outline for your text, making it more visible regardless of whatever background it's set on or borders/lines it crosses. Also useful for setting text anywhere that
isn't a speech bubble or plain surface, and the big shouts that explode outside speech bubbles.
I hope that was helpful. Look forward to more of your work.
ED: Found the page I learned this from. The "series" is a good brief lesson in typesetting in general.
