Naruto might approach Yagura with honesty. He would probably start by telling Yagura that he knows he's in a bad situation with the Akatsuki. Naruto could share his own story of being ostracized in Konoha at first and how he overcame it. This would make Yagura see that Naruto can understand his pain and might be more receptive to Naruto's help.
He expressed his love in many ways. For example, he was very concerned about Rin's well - being. Whenever she was in trouble, he would rush to her side without hesitation. He also blushed around her sometimes, which was a sign of his shyness and love for her.
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.
It could be that Yagura had some secret plans that would endanger the balance among the ninja villages. Naruto, having a strong sense of protecting peace, discovers these plans and decides that eliminating Yagura is necessary. For example, if Yagura was planning to use a powerful and dangerous jutsu that could destroy multiple villages, Naruto would act to prevent it even if it means killing him.
First, do a lot of research on Yagura. Know his character traits, his role in the Naruto world, and his relationships. Then, come up with a unique plot. It could be something that fills in the gaps in his story in the original series. For example, you could write about his internal struggles when being controlled.
The concept can be portrayed through emotional distance. Naruto might not understand Yagura's cultural background or the significance of certain things to him. This lack of understanding leads to neglect. For example, Yagura has his own history and traditions as the Mizukage, and if Naruto doesn't respect or take into account these aspects, it can create a sense of neglect in their relationship in the fanfiction.
Utakata is a character known for his unique abilities and often has a complex personality. In fanfiction, he can be a great protagonist or antagonist depending on the story. Yagura, on the other hand, also has his own set of characteristics and powers. He can be portrayed as a strong leader or a conflicted individual.
