The number of bullets necessary to kill God is

Heroes gathered from another world to slay the god that will destroy the world. The strongest swordsman wielding a holy sword, an elegant dragon knight commanding dragons, a witch who can decipher all phenomena in heaven and earth, a warrior worth a thousand soldiers, and... me, an FPS otaku (sniper specialist). Wait a minute. Something's wrong with my job compared to the others. But my protests fall on deaf ears, and I'm transported to another world. So I'm just a student, but—could it be that I can use FPS abilities? If that's the case, I'll show you what a real one-shot, one-kill looks like. Even if my opponent is an actual god.
