Well, there's 'Naruto and the Mysterious Kyoka Suigetsu'. In this fanfic, Naruto is on a mission and stumbles upon a hidden temple where the secrets of Kyoka Suigetsu are stored. He has to face many challenges and enemies who also want to get their hands on this powerful weapon/ability. Also, 'The Merge of Naruto and Kyoka Suigetsu' is quite fascinating. It imagines a scenario where Naruto somehow fuses with the power of Kyoka Suigetsu, resulting in a new and unique set of abilities that he has to learn to control while still staying true to his values.
In the Naruto universe, Karin seducing Suigetsu is more likely to be just a fanfiction concept. Their personalities are quite different. Karin is often very focused on Sasuke, and Suigetsu has his own goals and a rather brash personality. While in fanfiction, authors can create all kinds of scenarios for them to interact in a seductive way, it doesn't seem very likely within the main storyline's character dynamics.
In Naruto fanfictions, Kyoka Suigetsu usually works by creating extremely powerful illusions. It can make the target see things that aren't there or distort their perception of reality. For example, it might make an enemy think they are surrounded by their own allies when in fact they are alone.
One common plot is that Karin uses her unique abilities as a sensor - type ninja to get closer to Suigetsu in a seductive way. For example, she might sense his emotions and use that knowledge to her advantage. Another plot could be that they are on a mission together, and Karin decides to try and seduce Suigetsu to make the mission more interesting or to gain some sort of upper hand. Sometimes, it might also involve a love triangle situation where Sasuke is somehow involved, and Karin's seduction of Suigetsu is a way to make Sasuke jealous.
I'm not sure specifically what 'suigetsu visual novel' is about as there could be many visual novels with this name. It might be about a fictional world, perhaps with unique characters, a particular story arc like a mystery or a love story.
You could try looking for it on popular visual novel platforms. Some well - known ones are Steam, which has a large collection of visual novels. Another option might be to check on dedicated visual novel websites.
Naruto Naruto was a very popular Japanese manga and novel about how the protagonist Naruto grew into a powerful ninja and fought fiercely with other characters. Naruto had encountered many difficulties and challenges in his growth, including learning ninjutsu, becoming a ninja master in the ninja village, fighting with other ninjas, and so on. During his adventures, Naruto also made many friends and enemies, some of whom became important figures in his life. Naruto Naruto's novels had a compact plot and interesting stories that were deeply loved by readers.
He'd probably be super surprised. I mean, seeing yourself as the opposite sex is not something that happens every day. He might blurt out something like 'Who are you? You look like me!' and then start to realize the situation. He could be a bit embarrassed too, especially if female Naruto had some different mannerisms or ways of dressing.
I think Hinata could be an ally. She has always been in love with Naruto and would not stand by while he is in danger from Dark Naruto. Additionally, Shikamaru is smart and strategic. He might see the threat of Dark Naruto to the village and decide to assist Naruto, using his intelligence to come up with battle plans.
It depends on the specific plot of the fanfic. Sometimes he could be on a secret mission, in a hidden village, or facing a new challenge in an unknown location.
