Naruto could be extremely cautious at first. He knows that things related to the Uzumaki clan can be very powerful and potentially dangerous if misused. So, he would carefully examine the scroll without opening it right away. He would check for any traps or signs of danger. Once he is sure it's safe, he would then open it with great enthusiasm, knowing that whatever is inside could be a great asset to him in his journey to protect the village and become a stronger ninja.
He is probably very excited. Naruto has always been eager to learn new things and become stronger. Finding an Uzumaki scroll means he has the chance to discover something unique about his own clan, so he would be filled with anticipation.
In many fanfictions, Naruto's reaction is a mix of shock and determination. The shock comes from finally learning about his clan, and the determination is to uphold the Uzumaki name. He could start wearing something that represents the Uzumaki clan, like a symbol on his clothing. He also may become more protective of the Uzumaki secrets and legacies he discovers.
Naruto's reaction could be complex. On one hand, he would be happy to find someone else from his clan. He has always been proud of his Uzumaki heritage despite not knowing much about it at first. But on the other hand, he might be a bit cautious. Karin has been associated with some not - so - good groups in the past. However, overall, his positive nature would probably lead him to approach Karin with an open mind and try to build a connection with her based on their shared Uzumaki roots.
He probably gets very worried. Kakashi is Naruto's teacher and mentor, so he'd likely be immediately concerned and rush to Naruto's side to assess the situation.
Naruto would be cautious. He's been through a lot in his life, and he knows that powerful items often come with a price. He might start to investigate where the blades came from and what their purpose is. He'd also be thinking about how to keep them safe from his enemies. He doesn't want these blades to fall into the wrong hands. So, he'd be on high alert while also being intrigued by the potential power they hold.
Maybe it contains some long - lost jutsu. Uzumaki clan was known for their powerful sealing techniques, so it could be a scroll with a unique sealing jutsu that Naruto can learn and use to his advantage in battles.
He would be very angry. Naruto is not one to take betrayal lightly.
He could be very surprised at first. Maybe he's just out on a normal day in the forest and suddenly comes across a baby. His immediate reaction might be to look around for any sign of the baby's parents.
At first, Naruto might be a bit hesitant. He's not used to having something so personal from his parents. But then, his curiosity would get the better of him, and he would slowly unroll the scrolls, his hands trembling slightly as he realizes that he's about to learn things he has always dreamed of knowing about his parents.
He may show a rare moment of kindness. Given his own past traumas and experiences, he might empathize with Hermione on some level. He could offer her some words of wisdom or even some form of magical assistance to help her get better.
He might be initially startled. Snape is used to seeing Hermione as a strong - willed and confident student. So seeing her crying could catch him off - guard. But then he might quickly put on his usual cold facade and ask her curtly what's wrong.
