The anime and manga series Gantz features a large number of fictional characters created by Hiroya Oku. The series takes place in a modern Japan, in which several creatures known as aliens start attacking citizens.
The series starts with the teenager Kei Kurono, who dies in a train accident along with his childhood friend Masaru Kato. Suddenly, they appear in an apartment from Tokyo along with several people who have recently died. A black sphere named Gantz revives them and then it sends them messages, telling them they have to kill aliens if they want to live. All the participants are given powerful weapons such as guns, and black bodysuits that increase their strength. As the characters participate in the game, they start discovering more things related to Gantz such as what happens when they defeat several aliens, and why Gantz holds the game.
Names are in Western order, with the given name before the surname (family name).
When creating the chapters from the manga, the author Hiroya Oku first makes a draft of the pages. He then creates 3D models of the characters and backgrounds on his computers. Once done, Oku scans the characters draws he made in the 3D models, and the backgrounds are reduced to lines. Finally, he then adds tone to the pages and colors them, and starts adding sound effects as well as dialogues.
