In the fanfiction where Naruto has a heart disease, who would be most likely to help him?

Sakura would be a likely candidate. She's a medical ninja, and she has always cared about Naruto. She would use her medical skills to try and stabilize him.

Iruka sensei might also be involved. He has always been like a father figure to Naruto. He could give Naruto the confidence he needs and maybe even help him plan the location for the proposal, perhaps a place that has sentimental value for both Naruto and Hinata related to Naruto's early days at the academy.

His mentor, Kakashi, would also be there to help. Kakashi is very protective of Naruto. He would use his experience and calm demeanor to make sure Naruto gets the best possible care and support during this crisis.

Lisbon would probably be the first one to help. She has a deep connection with Jane and cares about his well - being.

Iruka sensei could also be very helpful. He has always been like a father figure to Naruto. He would support Naruto through this strange transformation, offering advice on how to handle the reactions of others in the village and how to adapt to this new situation without losing sight of his ninja goals.

Sakura is very likely to help. She's a skilled medical ninja and has always been there for Naruto. She would use her medical jutsu to try and heal his wounds. Kakashi too. He has a lot of experience and would be able to protect Naruto while he's injured. Also, Sasuke might come to Naruto's aid. Despite their past differences, they have a deep bond, and Sasuke would not let Naruto die if he could help it.

Iruka - sensei would be very likely to help. He was Naruto's first teacher and has always cared about him. He could use his teaching skills to reteach Naruto things he's forgotten. Hinata would also be there for Naruto. Her love for Naruto is strong, and she would do anything to help him. She might use her Byakugan to look for any physical problems in Naruto's body that could be related to his memory loss. And of course, Jiraiya. If he were still alive in the fanfiction, he'd be a great help. He trained Naruto and knows him well, so he could use his sage knowledge to assist in getting Naruto's memory back.

Ninjas, of course! They would come to relax after a long day of training or missions. Also, fans of the ninja world from within the story would be there. Maybe even some of the village leaders would stop by to show support for the local business.

Another possible antagonist could be a rogue ninja from Hailbel's past. This ninja could have a vendetta against her family or something she did in the past. When he discovers that Hailbel is with Naruto, he decides to take them both on. He might have some unique and dangerous techniques that Naruto and Hailbel have to figure out how to counter.

Hermione would definitely be one of the first to help. She's extremely intelligent and well - read in magic, so she'd quickly start looking for spells or potions to heal Harry. She'd also stay by his side to comfort him and keep his spirits up.
