From what I can gather, 'I am God Killer' might tell a story of a character who discovers their power to slay gods. This discovery could lead to a quest for knowledge about their own origin and the nature of the gods. Along the way, they may encounter different factions, some of whom revere the gods and see the protagonist as a threat, while others may see the protagonist as a savior. The plot could also involve moral dilemmas. Is it right to kill a god? What are the implications for the future of the world? And as the story progresses, the protagonist may face increasingly difficult challenges and enemies, both mortal and divine, as they strive to fulfill their role as the god killer.
You can try looking for it on major e - book platforms like Amazon Kindle or Barnes & Noble Nook. Sometimes, specialized light novel websites also have it available for purchase or even free reading in some cases.
Well, that depends on the plot and how the author has developed your character. Maybe you have god-like powers or are considered a god by others in the story.
