It could be Asuka from Senran Kagura. She is strong - willed and has a sense of justice similar to Naruto. When they meet, she might be the first to recognize his good qualities and start to develop feelings. She would be more likely to take the initiative compared to some of the other girls, so she could be the first to start a relationship - like connection.
Sasuke and Yomi would make a great pairing. Sasuke's brooding and power - hungry nature would be an interesting foil to Yomi's dark and mysterious personality. In a fanfiction, they could start off as enemies but gradually find common ground as they realize they both have a deep - seated desire for power and a complex past that has shaped them. They might end up teaming up against a greater threat in the combined Naruto - Senran Kagura universe.
In a Naruto and Senran Kagura harem fanfiction, it could start with Naruto being invited to a special ninja academy in the Senran Kagura world. The female students there are intrigued by his unique chakra and his experiences from his own world. They compete for his attention in their own ways, like some might show off their combat skills while others try to get closer to him through shared interests. Naruto, being a bit naive about relationships at first, slowly realizes that he has a special connection with each of these girls, creating a harem - like situation.
A possible fanfiction could be about a character from Naruto ending up in the world of Senran Kagura. Let's say Naruto himself gets transported there. He would be really confused at first by the different rules and the all - female cast (mostly). But then he starts to adapt and uses his shadow clone jutsu in creative ways during battles against the various enemies in the Senran Kagura world. He could also make friends with some of the characters and teach them about chakra.
Perhaps a plot where the Persona characters are invited to a special tournament in the Senran Kagura world. The tournament has strange rules that are different from what they are used to. As they participate, they start to notice some dark undercurrents. It turns out that an enemy is using the tournament to drain the energy of the combatants for a nefarious plan. The Senran Kagura and Persona characters must then put aside their differences and work together. The Persona characters can use their Personas to analyze the situation and the Senran Kagura characters can use their combat expertise to fight the physical battles.
First, decide on the crossover concept. As I mentioned before, it could be with a different game, anime, or genre. Then, research both the Senran Kagura world and the world you want to cross it with. Know the characters, their personalities, and their abilities. After that, create an outline. Plan the beginning, middle, and end of your story. Maybe start with how the two worlds collide or how the characters meet.
Naruto himself is obviously a key character in this type of fanfiction. Then there's Sasuke. Given his popularity and complex personality, he can add a lot of drama to the harem situation. Shikamaru is also likely to be part of it. His laid - back but intelligent nature can create interesting interactions with Fem Haku. Another one could be Gaara. His past and his new - found path of friendship could lead to him having feelings for Fem Haku in the fanfiction.
Kagura might interact with Sakura. Sakura, being a strong - willed and intelligent kunoichi, could offer her medical expertise to Kagura if she returned injured. Or they could have a girl - to - girl talk about their respective journeys in the ninja world.
It depends on your taste. Some people love the story of Senran Kagura, while others might not find it that appealing.
Yes, Senran Kagura does have a manga. It expands on the story and characters from the game series.
Well, Moka would be a likely candidate. She's the main female character in Rosario Vampire and her kind yet strong - willed nature could be attracted to Naruto's positive traits. Inner Moka might also be interested in his power. Tsukune's female friends like Kurumu and Mizore could also be part of the harem. Kurumu is very flirtatious and might see Naruto as an interesting new addition, and Mizore, with her cold exterior but warm heart, could gradually fall for Naruto as they interact more.
