Well, in a 'naruto and tenten family fanfiction', their children would play a big role. Let's say they have a son and a daughter. The son is very much into his father Naruto's Rasengan technique and is constantly trying to improve it. The daughter, on the other hand, is more interested in her mother Tenten's ranged weapon attacks. There could also be a neighbor, an elderly ninja who has a lot of stories to tell. This neighbor could be a source of wisdom for the family, especially for the children as they grow up and face different challenges in the ninja world.
Maybe Rock Lee could be an important character. He could come to the orphanage to help with the physical training of the orphans. He would be a great inspiration for them with his hard - working attitude. Also, Neji could be involved. He could use his Byakugan to keep an eye on the orphanage and make sure there are no threats approaching.
Obviously, Naruto and Tenten are the main characters. Naruto, the energetic and powerful ninja, and Tenten, the skilled weapon - using kunoichi.
In this type of fanfiction, it could be that Naruto and Tenten start a family in a post - war era. They adopt orphans from the war and raise them as their own. The family dynamic would be interesting as Naruto's boisterous and positive attitude would contrast with Tenten's more practical and down - to - earth nature. Their family would be involved in rebuilding the village and spreading peace, with the children learning important values from both parents.
Rock Lee could be one of the main characters. He's Tenten's friend, and he might interact with the little sister, teaching her some of his unique ninja philosophies or training techniques.
Ino might also be involved. She and Tenten are friends, and Ino could be there to offer emotional support, sharing her own experiences or just being a good friend during this new phase in Tenten's life.
Obviously, it's Tenten and Naruto. Tenten, with her skills and no - nonsense attitude, and Naruto, the energetic and sometimes mischievous ninja - in - training. Their interactions would be the focus of the fanfic, with Tenten trying to manage Naruto's behavior and Naruto likely trying to have as much fun as possible.
It could be Orochimaru. He might be interested in Tenten's unique weapon skills and Naruto's power of the Nine - Tails. He could try to capture them to conduct experiments on how to combine their powers for his own gain. He might create some sort of hybrid - clone with Tenten's weapon - using abilities and Naruto's chakra.
Naruto might be really confused at first. He's used to people being friendly or having normal crushes, but a yandere is a whole different level. He'd probably try to talk to her and understand why she's acting so strangely.
Well, there are several characters that could be in the harem. First, there's Temari. She has interacted with Naruto during the Chunin Exams and other events. Her strong personality and combat skills could make for an interesting dynamic in a harem story. Karin could also be a part of it. She has a connection to Sasuke, but in a different scenario, she could be attracted to Naruto. And then there's Anko Mitarashi. She's a bit of a wild card, but her unique personality and her role as a ninja could add a different flavor to the harem with Naruto at the center and Tenten also being part of it.
Maybe Rock Lee. He has always been very passionate and his positive energy could have attracted Tenten. Their friendship might have blossomed into a romantic relationship, resulting in her pregnancy.
