In this kind of fanfiction, Mizuki might save Naruto from a dangerous enemy attack. Maybe he uses his own skills to fight off the attackers who are about to harm Naruto.
It's possible that Mizuki has had a change of heart. He might have seen the error of his ways in the original story and now wants to make amends by saving Naruto. He could have reflected on how his actions in the past were wrong and this is his way of redeeming himself. In this fanfiction, he might be trying to create a new, positive relationship with Naruto based on mutual respect and friendship.
I really liked 'Mizuki's Redemption Arc'. In this fanfic, Mizuki realizes the error of his ways after his initial betrayal. The author does a wonderful job of writing Naruto's reaction to Mizuki's attempts at redemption. It's a heartwarming story that shows the power of forgiveness in the Naruto universe.
Friendship is likely to be a common theme as well. Writers might show Shinichi forming new friendships or strengthening existing ones. They could create scenarios where his friends support him through difficult times or vice versa. For example, his friends could help him when he is facing a tough challenge in his fictional life.
Well, there are different ways it can happen in fanfiction. One way could be that Naruto and Mizuki are in a battle, and during the fight, Naruto accidentally activates a latent ability that allows him to absorb Mizuki. Maybe there is some sort of ancient seal on Naruto that reacts to Mizuki's presence and starts the absorption process. Another possibility is that Naruto is exposed to a strange chakra - infused object that was once connected to Mizuki, and this object triggers the absorption.
A good Naruto and Mizuki fanfiction often has well - developed characters. Since Mizuki is a complex character with his own motives, exploring his psyche deeper than in the original series can make for an interesting story. For example, if the fanfic delves into his past and how it shaped his actions towards Naruto.
I don't have the exact answer for that. The outcome of their relationship could be influenced by various factors within the manga's story. You might want to look into the latest chapters or consult with other manga enthusiasts.
