One possible storyline could be that in a mission gone wrong, Kurenai accidentally uses a jutsu that ends up hurting Naruto. Maybe she misjudges the situation and her genjutsu affects Naruto in an unexpected and harmful way.
One possible storyline could be that Naruto is wrongly accused of a serious crime in the village. Everyone turns against him, even his friends. He might be shunned and face physical attacks from villagers who once feared or respected him. Naruto would then have to struggle to prove his innocence while dealing with the emotional pain of being betrayed by those he cared about.
One possible reason could be a misunderstanding. Maybe Naruto was misidentified as a threat in a tense situation. For example, if there was some sort of dark jutsu at play that clouded Kurenai's judgment and made Naruto seem like an enemy. Another reason might be that Kurenai was under some sort of mind - control. There are many villains in the Naruto universe who are capable of such things. If she was being controlled, she might unknowingly attack Naruto.
One possible plotline could be Naruto growing up in a more nurturing environment. He might learn different jutsu from Kurenai and Anko. For example, he could pick up some of Kurenai's genjutsu skills, which would add a new dimension to his fighting abilities. Anko could also teach him some of her more unorthodox and aggressive fighting styles. Another aspect could be how Naruto's personality is influenced by these two strong female characters. He might become more in - touch with his emotions and develop better relationships with others in the village.
One possible storyline could be a story of friendship and alliance. Maybe Naruto and Kurenai team up with an Akatsuki sister who has a change of heart. They could fight against the more evil elements within the Akatsuki together.
Well, in some fanfics, Sakura might be jealous of Naruto's growing power and relationship with others. So she could try to undermine him, which in turn hurts Naruto. Maybe she spreads false rumors about him in the village. Another idea is that Sakura is forced to choose between Naruto and Sasuke in a dangerous situation, and her choice, even if it's not completely her fault, ends up hurting Naruto deeply. It could also be that Sakura's overzealous medical treatment, in an attempt to save Naruto from a serious injury, actually causes him more pain and harm.
In a fanfiction, the Nomu could be controlled by a hidden villain who wants to break Izuku's spirit. So, the Nomu injures Izuku in a brutal way. This forces Izuku to re - evaluate his approach to heroism and his relationships with his friends and mentors. He may have to find new ways to heal and grow stronger, both physically and mentally.
One possible plotline could be that Kurenai becomes possessive over Naruto due to seeing his potential. She might take it upon herself to train Naruto more rigorously than others, which could lead to Naruto growing stronger in unique ways. For example, she could teach him some of her genjutsu secrets, and as he masters them, their bond grows stronger, making her even more possessive of his growth and success.
One possible storyline could be that Naruto's red hair is a sign of some special power or lineage. Maybe it links him to a long - forgotten clan.

One possible storyline could be Naruto teaching Temari new ninja techniques. Since Naruto has his own unique and powerful skills like the Rasengan, he could pass on some of his knowledge to Temari. For example, he might show her how to infuse wind chakra in a different way into her weapons, enhancing their power. This could lead to Temari developing new jutsus and becoming even stronger in combat.
One possible storyline could be Maia getting hurt during a courtroom battle. Maybe she is physically attacked by an angry client or a witness.
