Well, Naruto has a lot of unique abilities. He could enter Sage Mode and use his enhanced perception to outmaneuver Obito. Konan, on the other hand, is a very skilled fighter herself. But against Obito's Sharingan and his space - time ninjutsu, she might be at a disadvantage. Naruto could use his talk - no - jutsu to make Obito realize the error of his ways and stop attacking Konan. This would be a very Naruto - like way to end the confrontation.
Naruto's character could develop a deeper sense of responsibility. Saving Konan from Obito would show that he is not only protecting his close friends from Konoha but also those from other villages. This would expand his view of what it means to be a hero.
One idea could be that Naruto uses his shadow clones to create a distraction while he sneaks in to save Konan. He could use his Rasengan to take out Hanzo's guards quickly.
One key moment could be when Naruto jumps in front of a fatal attack aimed at Konan. His quick reflexes are crucial here. He takes the hit or deflects it using his own skills, like his shadow clone technique to create a distraction and then save Konan.
In some fanfictions, Konan might use her origami techniques in a highly lethal way. Maybe she creates a large number of explosive paper bombs and traps Obito in a confined space, detonating them all at once to overpower his defenses and kill him.
In this fanfiction, Naruto may save Konan through his ability to understand and connect with people. Maybe Konan is in a psychological crisis, feeling lost or conflicted. Naruto, with his kind heart and his own experiences of overcoming hardships, talks to Konan. He gives her the strength and hope she needs to get out of her difficult situation. His words are like a life - saving jutsu, bringing Konan back from the brink and saving her in a very different, yet equally important way.
It might be for the greater good. If Obito's actions in the fanfic are leading to destruction on a large scale, Konan, being a protector of sorts, decides to take him out to save the world or at least her part of it.
Their interaction would be intense. Konan saving Naruto would put them in a situation where they have to rely on each other completely. Naruto would be in awe of Konan's abilities, especially her ability to control paper. Konan would be impressed by Naruto's willpower. They might have some light - hearted moments too, like when Naruto tries to make Konan laugh with his goofy antics, which would help break the ice between them during their dangerous situation.
One possible plot twist could be that Konan discovers a hidden power within Naruto that even he doesn't know about. Maybe it's a connection to an ancient and forgotten jutsu. This could change the whole dynamic of their relationship and the way she saves him. For example, she might have to protect him not just from physical harm but also from those who would want to use this power for evil.
