One possible storyline could be that Naruto, with his ability to teleport and his powerful ninjutsu, senses Mikasa in danger in the Attack on Titan world. He quickly arrives, uses his Rasengan to defeat the Titans surrounding her. Then he takes her to safety and they form an unlikely friendship, with Naruto sharing his experiences of fighting for his village and Mikasa being amazed at his powers.
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.
One great Naruto and Mikasa fanfiction is 'The Unexpected Alliance'. In this story, Naruto somehow finds himself in the Attack on Titan world and teams up with Mikasa. It's really interesting to see how their different skills and personalities interact. The author does a great job of keeping both characters in - character while also creating a new and exciting plot.
Perhaps Anko is trapped in a genjutsu and Naruto uses his own experience with breaking free from illusions to save her. He could sense her distress and use his chakra to disrupt the genjutsu, freeing Anko. This would show Naruto's growth and his ability to help those in need, even a more experienced ninja like Anko.
It's also about the characters themselves. Naruto is this energetic, optimistic guy who never gives up, while Mikasa is more reserved and focused on protecting her loved ones. Their different personalities can lead to some great character development and interactions in fanfiction. For example, Naruto could inspire Mikasa to be more open, or Mikasa could teach Naruto some new combat strategies.
One good Naruto Mikasa fanfiction could be a story where they meet in a crossover world. Maybe Mikasa is on a mission in the Naruto universe and she teams up with Naruto to fight a common enemy. They start off as strangers but gradually learn from each other's skills and values.
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 a Naruto Saves Pyrrha fanfiction, it could be an interesting crossover. Naruto, with his powerful ninja skills, might save Pyrrha from a variety of threats. Maybe she's in a battle in her own world and Naruto's teleportation jutsu allows him to appear just in time. It could also be that Pyrrha is facing some sort of internal struggle, like self - doubt, and Naruto's indomitable spirit inspires her to overcome it.
Well, Naruto saving Shisui in a fanfiction could be really interesting. Naruto is known for his never - give - up attitude. If Shisui is in some sort of genjutsu - related trouble, Naruto could use his own strong will, which he has shown against powerful genjutsu like Itachi's Tsukuyomi, to break Shisui free. And his Sage Mode would give him an extra edge in combat if there are opponents to fight off while rescuing Shisui.
Well, in a fanfiction scenario where Naruto saves Sakumo, it could be that Naruto has mastered some new jutsu that allows him to enter into Sakumo's mind. Sakumo was in a very dark place after being shamed by the village. Naruto could use this jutsu to show Sakumo that there is still hope and that his worth is not defined by the village's opinion. Then he could bring Sakumo back to a positive state of mind and save him from self - destruction.
