Gantz TPB Volume 15 (Mature)

"Gantz is getting absolutely intense! Our protagonist, the eternally awkward otaku boy named Kei, has hunted a bevy of odd and dangerous aliens living in Japan. The Onion Alien was strange enough, but then there were the dinosaur aliens and eventually some vampires who might not be aliens at all. Gantz moves along at a furious pace, drowning readers in blood and violence, but then holds back for a few tender (and sometimes excessively sexy) moments here and there. It's a crazy ride so far, a guilty pleasure for many readers. See whom Kei is told to hunt next! It will certainly be a surprise."
