Naruto died in the manga because he gave everything he had to ensure the safety and peace of his world. The battles were extremely demanding, and his body and chakra couldn't handle the strain anymore.
Minami was an important character in Naruto. She was one of the ninjas from the hidden village of Kiba, and also Hirotomaru's mentor and companion. Minami was an outstanding ninja with superb combat skills and medical abilities. She had performed well in many battles and made great contributions to the hidden village of Kiba.
In the plot, Minami had once been on a mission with Hikari Maru. During a battle with the village, Minami was unfortunately stabbed by the sand iron of the village, causing her to be paralyzed. Although Xiao Nan was very strong, she still needed medical treatment to recover her health.
However, after a battle with Shayin Village, Xiao Nan was unfortunately killed by the enemy. Her death was very cruel. The enemy shot her in the head with a poisonous arrow, which eventually led to her death. Even though Minami was once an excellent ninja, her death was still a very tragic thing. Her sacrifice also brought a heavy blow to the hidden village of Kiba.
In some Naruto fanfictions, Jiraiya's death might be different from the original. One common way is that he might have had more backup during his fight with Pain. Maybe some new characters created in the fanfiction came to his aid at the last moment, preventing his death. However, in other fanfictions, his death could be even more tragic, like being betrayed by someone he trusted before facing Pain, which weakened him and led to his ultimate demise at the hands of Pain.
Well, in some possible versions of this fanfiction, Naruto might die from a powerful enemy ambush in the gorge. Maybe a group of rogue ninjas with strong and unexpected jutsus caught him off - guard.
