In this fanfic, it could be that Tsunade is training Naruto and Futa at the same time. They have different strengths and weaknesses. Tsunade has to come up with a training regime that caters to both of them. This could lead to some friendly rivalries between Naruto and Futa, and also some interesting character development as they learn from each other and from Tsunade.
Perhaps in the fanfic, Futa is a new character in the Naruto world who has some sort of connection to Tsunade's past. Naruto gets caught in the middle of their relationship. It could involve Futa having some secrets that Tsunade is desperate to know, and Naruto helps in uncovering those secrets while also growing as a ninja himself.
One possible plotline could be Tsunade teaching Naruto more about medical ninjutsu. Since she is a great medical ninja, she could pass on her knowledge to Naruto, which would add a new dimension to his skills. Another aspect could be her guiding Naruto in leadership, as she is the Hokage. This might help Naruto in his future role as a leader in the village.
A plotline could revolve around Sakura trying to understand Tsunade's past more deeply. Tsunade might be reluctant at first, but as they work together more closely, she starts to open up. This could lead to Sakura learning important life lessons from Tsunade's experiences, like how to deal with loss and keep going. They could also get into a situation where they have to use their combined medical and combat skills to save a group of injured ninjas.
One possible plotline could be that Tsunade and Naruto go on a dangerous mission together and Tsunade has to protect Naruto at first, but then Naruto's growth allows him to contribute significantly. Another could be that Tsunade is teaching Naruto some special medical jutsu, and they have a mentor - mentee relationship throughout the story.
Another plotline might be that Tsunade is affected by some kind of dark magic or genjutsu that makes her turn against Naruto. Naruto, realizing it's not really Tsunade's fault, still has to fight her to try and break the spell. He could call upon his friends for help, but in the end, it's his determination and his bond with Tsunade that helps him reach her and break the control.
One possible plotline could be that Naruto leaves with Tsunade on a mission to find a rare herb that is said to have the power to heal any wound. Along the way, they face various enemies who also want the herb for their own malicious purposes. Naruto's skills and Tsunade's wisdom would be put to the test as they battle their way through.
A possible plotline could be about family secrets. Tsunade might reveal some long - hidden family secrets to Naruto that change his perspective on his family and his place in the village. For example, she could tell him about a special kekkei genkai that runs in the family that he might inherit.
One possible plotline could be Naruto feeling extremely lost and having to find his own way to become stronger without their guidance. He might start to question his own worth and abilities, but then he could meet new allies who help him realize his true potential on his own. For example, he could encounter some other outcast ninja who have their own unique skills and together they form a new kind of ninja team that challenges the traditional ways of the ninja world.
One possible plotline could be Naruto growing up with a different set of skills influenced by Tsunade. Since Tsunade is known for her medical ninjutsu and super strength, Naruto might have an earlier inclination towards medical skills. He could be trained in a more balanced way between combat and healing. For example, in battles, he not only uses his regular jutsu but also heals his comrades instantly on the spot. Another aspect could be the political influence. Tsunade being an important figure in the village, Naruto might have a different standing in the village hierarchy from the start and face different kinds of challenges related to leadership and decision - making.
One possible plotline could be a comical take where Naruto, perhaps as a baby or in a situation where he's regressed to a younger state in diapers, accidentally uses his newfound baby - like clumsiness to his advantage in a prank - like way against his friends. For example, he might 'accidentally' spill something on someone while being carried, leading to a series of funny events.
One possible plotline could be that Naruto and Ino are on a mission together. They start off bickering like they used to in the original series, but as the mission progresses, they begin to understand each other better. For example, they might face a powerful enemy that forces them to rely on each other's unique skills. Naruto's brute strength and Ino's mind - control abilities could complement each other in combat. Another plotline could be a more emotional one where Ino helps Naruto deal with his inner demons related to his past. She could use her skills to get inside his head in a more positive way and help him come to terms with things.
