One possible plot could be Naruto using his positive energy to cheer up the orphans. He might tell them his own story of growing up alone and how he overcame difficulties. This would inspire the orphans and create a warm and hopeful atmosphere in the orphanage.
Well, one possibility is that Naruto uses his own experiences as an orphan to create a warm and supportive environment in the orphanage. He might teach the kids ninjutsu skills and also important life lessons about friendship and perseverance.
His kindness would be a major trait. He'd be very gentle and patient with the orphans, always there to listen to their problems. For example, if an orphan is sad about not having a family, Naruto would sit with them and share his own feelings of loneliness as a child.
Perhaps there could be a situation where the kids get into trouble, like accidentally releasing a small animal from a cage. Naruto would then have to use his quick thinking and ninja skills to catch the animal and keep the kids safe at the same time. This would show his ability to handle unexpected situations while babysitting.
In a 'naruto and tenten orphanage fanfiction', it could be that the orphanage is already existing but in a bad state. Naruto and Tenten volunteer there. Naruto uses his shadow clones to help with the heavy lifting and cleaning, while Tenten uses her connections to get better supplies. They start to form strong bonds with the orphans, and Naruto might even teach them some of his signature jutsu, like the Rasengan in a safe and controlled way. The story could also involve the orphans facing some challenges from outside the orphanage, like bullies, and Naruto and Tenten protecting them.
Maybe it could be about the adventures they have in the orphanage. They might discover some secrets within the orphanage walls.
One possible plot could be about an orphan in the My Hero Academia world who discovers they have a latent but extremely powerful quirk while living in the orphanage. They then attract the attention of various heroes or villains, and the story could revolve around their journey to understand their power and decide which side of the hero - villain spectrum they will be on.
The 'naruto brother of the orphanage fanfiction' might revolve around Naruto's bond with the orphans. It could explore how his own experiences of being an orphan shape his interactions with them. He might be a role model for the kids, showing them that no matter where they come from, they can achieve great things. It could also have elements of adventure, with Naruto taking the orphans on small adventures around the village, teaching them about the world outside the orphanage walls and giving them a sense of freedom and possibility.
One idea could be Naruto using his shadow clone jutsu to handle multiple kids at once. He could make clones to play different games with the children, like one clone for tag and another for hide - and - seek.
Kakashi could be an interesting babysitter. He has a lot of experience as a ninja and could teach Naruto a great deal while babysitting. He is also quite laid - back in his own way, which might be good for Naruto. Tsunade could also be considered. She is strong and could protect Naruto well. And she might be able to teach Naruto some things about leadership and responsibility while taking care of him.
Maybe he was blamed for some trouble he didn't actually cause. For example, if something went missing in the orphanage and the caretakers wrongly thought Naruto took it.
