Maybe Naruto uses his shadow clone jutsu to surround Ichigo and keep him safe from any approaching threats. The clones can act as a first line of defense, alerting Naruto of any danger.
One idea could be that Ichigo and Naruto are brought together by some sort of interdimensional rift. They initially don't understand each other's powers but soon realize they share a common goal of protecting their friends and worlds. They could team up to fight a powerful enemy that threatens both their universes.
Yes, there are quite a few out there. Some explore the idea of Naruto being a big fan of Ichigo. They often create crossovers where Naruto might be inspired by Ichigo's fighting style or his sense of justice. For example, in some fanfics, Naruto tries to incorporate Ichigo's sword - fighting techniques into his own ninja moves.
A more serious fanfic could be set in a post - apocalyptic world that was destroyed by a combined force of villains from both Naruto and Bleach universes. Naruto and Ichigo are the last hopes. They meet and initially clash due to their different ways of fighting and beliefs. But they gradually learn from each other and combine their powers in a unique way to take on the remaining villains and try to restore their worlds.
Yes, there are likely such fanfictions out there. Fanfiction writers often come up with creative and crossover ideas like this. You can try searching on popular fanfiction websites.
One great Naruto Ichigo fanfiction is 'The Crossover of Destiny'. It combines the unique powers of Naruto and Ichigo in a really exciting way. The story has a lot of action scenes where they team up against common enemies.
The cultural differences between their worlds might pose a problem. Naruto comes from a ninja world with its own set of rules and ethics, while Ichigo is from a world of Soul Reapers. Naruto might accidentally break some unspoken rules in Ichigo's world while trying to protect him, which could make things more difficult.
At the start, Ichigo would be defiant. He would not show any fear in front of Aizen. He might taunt Aizen, trying to get him to reveal his true intentions. As time goes on, he would start to feel a sense of isolation, but this would only strengthen his resolve. He would use his inner Hollow powers more freely, as he has no other option. He would also be constantly thinking about ways to turn the tables on Aizen and escape, and would be ready to take on any challenges that come his way during his captivity.
Eventually, Naruto could grow resentful. If the ignoring persists for a long time, he might start to think that Kakashi doesn't care about him at all. This could change Naruto's attitude towards Kakashi and might even make him more rebellious in his training or actions. However, deep down, he still probably hopes for Kakashi's recognition and approval.
Naruto would probably be extremely hurt. He has always considered Hinata a friend and perhaps more. Betrayal from her would be a huge blow to his trusting nature. He might initially be in denial, not wanting to believe that Hinata could do such a thing.
