In this fanfiction, Naruto might feel extremely lonely at first. He would have no one to share his ninja dreams or have friendly competitions with. He might spend his days exploring the now-empty villages, reminiscing about the old times with his friends and comrades.
Well, the plot could be that Naruto is the sole survivor after some kind of apocalyptic event. Maybe all the other shinobi were wiped out by a powerful enemy or a deadly disease. Naruto then has to find a way to rebuild the world while also dealing with his loneliness and the memories of his lost friends.
Another possibility is that Naruto himself could be his own antagonist in a sense. His loneliness and the weight of being the last man on earth could drive him to the brink of madness. He might have to fight his own inner demons, which could be manifested as a dark version of himself that wants to give up on the world and just let it decay.
Naruto might become more introspective. Without others around, he has to look inward more. He could be less of the loud, outgoing Naruto we know as he has no one to be that way for.

He may also experience many moments of pain, loneliness, and despair because he has no one else to communicate with and help him.
However, he might also discover some unexpected secrets and opportunities. He might discover relics and relics on Earth and learn about the history and development of this civilization. He might also find some precious resources such as rare metals or precious cultural relics to change his living conditions.

I don't think it's among the most popular types. While the 'last man standing' concept can be exciting, the 'lemon' aspect might limit its mainstream appeal as it often implies more mature or niche content. Most Naruto fans are probably more interested in action - packed adventures, character development, or the main story arcs.
The 'the last man on earth shortest horror story' is likely to focus on the psychological horror of the situation. The man is the sole survivor, and he has to deal with not only the physical world around him but also his own mind. He might start to question his own sanity. For example, if he sees something out of the ordinary, he has no one to confirm if it's real or just his imagination. He also has to face the finality of being the last, with no hope of a future for humanity as he knows it.
Another story could be his encounter with other forms of life. Maybe he discovers a group of mutated animals and has to figure out how to co - exist or avoid them. It adds an element of danger and mystery to his already difficult situation. He might also start to question his own humanity in the face of such extreme isolation.
I'm not entirely sure as the 'last man on earth Karl story' could be many things. It might be about a man named Karl who is the last person alive on earth. Maybe it involves his struggle for survival, his loneliness, and how he copes with a world that has no other humans.
