isn't this the first time Angelika has actual speech bubbles? til now her talking was only ever implied wasn't it?
No, she did spoken a very few times actually, just that she's super shy, so she mostly spoke in "gestures" instead to convey what she wanted to others (she has actually "spoken" with the girls after the whole labyrinth stampede thing that she came from)
She did spoke to Haruka back at his hideout from the beginning chapter when they went back there to clean it up a bit (that's when she first talked with him) but after that, it's mostly been her communicating through gestures with others (and she may occasionally actually speak) like she did here, they're a rare to hear (like Haruka said, in pg.4, it's been a while since the last time he heard her spoke)
Compared to "Dancer Girl" Nefertiri, who'd usually speak every now and then
