lol i feel like such a jerk for thinking this, but after seeing the new illustration of Koneko and her bigger breasts.. i feel like it might somehow be another error by the illustrator (like how there was once an error with Ravel's breast size) or somehow her senjutsu training is affecting her breasts when she is channeling senjutsu and its not that her breasts actually have grown.

though now that i think about it my second theory make me think it might also apply to Kuroka, since her breasts are so big, maybe her mastery of senjutsu has cause them to develop so much.
