Now updated for volumes 9-16.
Gantz (16 volumes out of 37, ongoing)
An anime classic known for deranged drama and extreme content. Mangaka Oku Hiroya has always loved big boobs and even this gory survival-horror manga is no exception.
Hiroya had previously done ecchi works, including one of my favorites, Hen. He draws the strangest looking boobs, but once I got used to it, I came to really like his style.
The story of Gantz doesn’t leave much opportunity for fanservice, especially when the shit hits the fan and Gantz swings into full on gory action mode. Hiroya can hardly stand to repress his inner perv though, and even during these action heavy chapters he finds ways to add fanservice by having some stand alone super-sexy pictures as chapter buffers.
