The plot might involve Kenshin traveling to a future where the dark forces he once fought have resurfaced in a new form. He then has to team up with descendants of his old friends to defeat this new threat, all while dealing with the strange new technology and social structures of the future world. For example, in this future, there could be advanced weaponry that he has to learn to counter using his swordsmanship skills. He also has to adjust to the different values and beliefs of the people in this new era, which may or may not align with his own.
Perhaps in this time - travel fanfiction, Kenshin is brought to a future where his legend has been distorted. He has to set the record straight and in the process, discovers a plot by an evil organization that wants to use his name for their own nefarious purposes. He must then use his skills and his code of honor to expose the truth and save the future from falling into chaos.
One possible plot could be that Kenshin is sent to a future where his past actions have had far - reaching consequences. Maybe his vow to not kill has inspired a new generation of warriors, and he has to adapt to a world where his skills are both revered and feared in new ways.
It could be a descendant of one of the old villains. For instance, if there were some remaining followers of Shishio who held a grudge against Kenshin, they might have passed down their hatred through generations. And in the future, a particularly powerful and vengeful descendant decides to take on Kenshin once he arrives in the future.
One great 'Rurouni Kenshin' time - travel fanfiction is 'Back to the Beginning'. It takes Kenshin back to his early days as a hitokiri and shows how his modern - day self copes with the past. Another interesting one is 'Time's Twist' where a modern - day character travels back to the 'Rurouni Kenshin' era and gets involved with Kenshin's journey. There's also 'Journey Through Time' which has a unique take on time travel in the 'Rurouni Kenshin' universe.
A common theme is redemption. For example, Kenshin might go back in time to right some of his past wrongs as a hitokiri. Another theme is self - discovery. When a character travels to a different time in the 'Rurouni Kenshin' universe, they often learn more about themselves. Also, the theme of changing the course of history, like preventing certain battles or tragedies from happening in the story's timeline.
Another theme is the exploration of Kenshin's dual nature. His kind - hearted self and his violent past as Battousai. Female - written fanfictions may focus on how a female character tries to understand and accept both sides of him, which can lead to some really interesting character development and plotlines.
One possible plot could be that a rival group of Kenshin's enemies kidnaps Kaoru to lure him into a trap. They might hold her in an old, abandoned building. Kenshin would then have to use his skills and enlist the help of his friends like Sanosuke to find her. The kidnappers could demand that Kenshin give up his sword in exchange for Kaoru's safety.
Well, in 'Rurouni Kenshin: The Legend Ends' story, Kenshin is in a fight against Makoto Shishio. Shishio wants to take over Japan and Kenshin has to stop him. Along the way, Kenshin's friends like Kaoru are there to give him moral support. Kenshin uses his unique swordsmanship skills. There are intense fight scenes that show Kenshin's growth as a character from his days as a feared assassin to a protector. It's also about his inner struggle to keep his vow of not killing again.
There's also 'Kenshin and the Unseen Bond'. In this fanfiction, a female protagonist forms an unexpected bond with Kenshin. It delves into how their relationship develops over time, with her being both intrigued and inspired by his code of honor. The story has some really interesting character interactions.
One idea could be that the OC is a foreigner who comes to Japan and gets caught up in the events around Kenshin. They might initially misunderstand his ways but gradually come to respect and even fall in love with him as they see his true nature.
Survival is also a major theme. The hurt character has to fight not only the physical pain but also the will to survive. They often face internal demons that question their worthiness of living. This is seen when some characters in rurouni kenshin hurt fanfictions struggle with their self - identity after a near - death experience.
One common theme is redemption. Since the main character Kenshin has his own journey of redemption, OCs often have similar arcs. For example, an OC might have a dark past and tries to make up for it in the world of Rurouni Kenshin. Another theme is love. It could be the love between an OC and one of the main characters, or the love for the new life they find in this universe.
