Well, Naruto would probably be really confused at first. He comes from a world of ninjas and chakra, and The Last of Us is a post - apocalyptic world full of infected and survival struggles. But being Naruto, he'd also be curious. He might be shocked by the violence and the desolate nature of the world in the fanfiction. He'd likely try to find some way to bring hope to the characters, like he always does in his own world.
The Last of Us was not a comic originally. It was first developed as a video game, which gained significant popularity and later inspired other related media, but the comic came later.
The duration of the story in The Last of Us depends on several factors. If you rush through the main quests, it could be around 12 hours. But if you take your time, do side quests, and explore the environment thoroughly, it could stretch to 25 hours or more.
