At first, Harry would be shocked. Fanfiction wasn't something he was used to in the wizarding world. But then, he might start to think about how much Sirius meant to so many people that they would write stories about him. He could see it as a kind of tribute in a way. However, he might also be a bit protective of Sirius's memory. He wouldn't want people making up false things that could damage Sirius's reputation. So he might be a bit conflicted, but ultimately interested in this new discovery.
Harry would likely be quite curious. He'd want to know what these fanfictions were about. Maybe he'd be a bit cautious at the same time, worried that some of the fanfictions might distort Sirius's true character. But overall, I think he'd be intrigued and might even try to find a way to read some of them, just to see what the fuss was all about.
Well, Harry might start to look at Sirius in a new light. He could see him not just as his godfather, but as a figure that inspired creativity in others. This could lead to Harry wanting to learn more about Sirius's past, things that might not have been covered in the original stories he knew. And it could also lead to him having more conversations with people who wrote or read the fanfiction, getting new perspectives on Sirius.
Harry might be initially shocked. He could feel a mix of sadness and a sense of responsibility. After all, Sirius was like a father figure to him.
Harry Potter's reaction would depend on his mood when he finds the manga fanfiction. If he's in a relaxed state, he might be more open - minded and excited to explore this new form of storytelling. He'd notice the detailed art and different character designs. He may be a bit thrown off by the different magic concepts or lack of wands in the manga. But overall, he could grow to like it, especially if there are elements of adventure and mystery, which he loves. He might even start sharing some of the interesting parts he finds with his friends at Hogwarts, like Hermione, who would also be interested in analyzing the different narrative styles.
Sirius would probably be very worried and immediately try to help Harry. He might use some basic healing spells he knows.
His life would become more complex. He would have a new family bond to consider. He'd likely be more protective and might start to think about his future in terms of his sister as well.
They might be a bit surprised at first. But then they would probably be understanding. Hermione, for instance, might be interested in the literary aspects of the fanfiction he likes. Ron, on the other hand, might tease him a bit but still support his interest.
At first, Harry would probably be in shock. He's been through so much in his life, and this would be a huge new development. He might be a bit hesitant and scared, not sure if he's ready to be a father. But as time goes on, his Gryffindor courage would kick in and he'd start to take on the role with determination.
He could be shocked. Maybe he'd laugh it off if it was a funny or light - hearted fanfiction.
Sirius might react with a mix of surprise and protectiveness. He would be like an older brother or father figure. He'd make sure they were safe and not doing anything too risky.
Sirius would likely be extremely angry. He already has a protective streak towards Harry. He might immediately confront those he suspects of the abuse, whether it's the Dursleys or others at Hogwarts. He would probably also try to remove Harry from the situation as quickly as possible.
