Take GTO remove the crapy art work and the great teacher himself replace it with the sensie from Kodomo no Jikan and the art work (panty shots gicen extra attention ofcourse) and what do you get? A manga hummurous at times, perversion reaching the limits of what could be called non-hentia at others, and generally a good light read. The mangaka is not going to be winning any litterary awards for this one but for what it is, it is well done. The story and charrachter progression could be better but we'll forgive that and appreciate this work for its ecchiness of which is donemasterfully. The series is still ongoing so we can't really judge it completely but from what i have read, 28 chapters, its enjoyable.
