Maybe the woman is being held captive by a powerful and evil ninja. Naruto discovers her situation and infiltrates the enemy's hideout. He battles the guards and finally reaches the woman. As he frees her, she reveals that she has a special power that can help Naruto in his fight against a greater evil. So, they form an alliance. This shows how Naruto's act of saving her not only helps her but also benefits his own goals in the long run.
Well, Naruto could save a woman who is trapped in a collapsing building during an enemy attack. He could use his super strength and speed to get her out safely. Then, the woman might be so grateful that she offers to help Naruto in his future missions in some way, like providing him with valuable information about the enemies.
In a different take, the woman could be in a spiritual or magical danger. For example, she is being possessed by an evil spirit. Naruto, with his strong will and chakra, manages to expel the spirit and save her. After that, the woman, who has some knowledge of ancient jutsus, teaches Naruto a new and powerful technique as a token of her gratitude. This enriches Naruto's skills and makes him even more powerful for future battles.
One possibility is that Naruto uses his Shadow Clone Jutsu to create distractions while he rescues Pyrrha from a trap. Since he's so good at this jutsu, he can easily outwit the bad guys. Pyrrha, on the other hand, might be able to assist Naruto once she's free, using her weapon skills.
Perhaps Naruto saves Shisui from a group of rogue ninjas. He uses his speed and agility, enhanced by his training with Jiraiya, to quickly reach Shisui. His Nine - Tails chakra could also flare up, intimidating the enemies and giving him the power to fight them off.

They could come up with a complex plan to save Asuma from whatever danger he is in, like a deadly curse or a powerful enemy's attack.
In a 'Goku Saves Naruto' fanfiction, Goku might teach Naruto some of his unique fighting techniques. Since Goku has such a vast knowledge of martial arts and energy control, he could help Naruto become even stronger. For example, he could show Naruto how to better control his chakra using the principles of ki control. And also, Goku's fearless attitude in battle could inspire Naruto to face his enemies more bravely. Goku could also use his Dragon Balls to wish for something that would benefit Naruto or his village, like restoring the damage done by a powerful enemy attack.
It could also result in a change in the way the village views their relationship. Since Naruto is a hero, his saving of Hinata would be a big deal. This could lead to the village elders or the people in general being more accepting of a possible romantic relationship between them. For example, they might start to see Hinata as a more important figure in Naruto's life and give her more respect.
Well, Naruto could use his Nine - Tails chakra to create a powerful shield around Mikasa when the Titans are attacking. This would protect her from their attacks. Then he could use his chakra arms to grab onto nearby buildings and swing them both to safety.
