To OP. I don't know how big of a fucking moron you are but the pic you posted is of Negima!? NOT AKAMATSU'S WORK!
Mahou sensei Negima! however is his work.
As for the breasts. he has been known to slip a nipple in every so often. Volume 4 of Mahou Sensei Negima when Setsuna walks into to take her bath. When she dumps a bucket of water on herself you can see a small nipple.
