GIGANT manga volume 4 features story and art by Hiroya Oku, the author of the top-selling title Gantz.

The end of the world is in full swing, with the spiteful users of E.T.E. voting for more and more disasters to be visited upon Tokyo. While Chiho remains unjustly imprisoned as a criminal, the armed forces of the JSDF do their best to defend the city against killer titans, robots, and worse. As the situation spirals out of control, even if she does make it out of prison, will one giant woman really be enough to turn the tide?
