He might face distrust from some members who are cautious about his connection to Voldemort. Since Harry has a unique bond with the Dark Lord, some in the Order could be worried that he might be used as a tool against them.
Some members may be immediately welcoming and eager to assist. They recognize Harry as an important figure in the fight against Voldemort and understand his need for support.
One challenge could be dealing with other students who don't understand his over - protective attitude towards Harry. Some might think he's being too nosy or interfering. Another might be that he has his own studies and responsibilities at Hogwarts which could sometimes conflict with his protection duties.
He would face the challenge of learning a new curriculum. Different schools may have different focuses in magic education. For instance, some might emphasize more on ancient spells while others on magical theory. Also, he might have trouble with the new social hierarchy. In Hogwarts, he is known for his deeds, but in a new school, he has to start from scratch and earn respect. There could also be differences in the use of magic wands or other magical tools that he needs to adapt to.
One challenge would be making friends. The students at Mahoutokoro might have different values and social norms compared to Hogwarts. He might find it difficult to fit in and find a group he belongs to. Additionally, the academic system could be very different. The grading system, the types of courses, and the way knowledge is imparted could all pose difficulties for Harry.
He might face the challenge of acceptance. The Snape family may be hesitant to welcome Harry, given Snape's complex relationship with him at Hogwarts. Also, there could be differences in magical practices. The Snape family might have their own unique ways of doing magic that Harry has to adapt to.
One major challenge is Harry's initial distrust. Harry has known Snape as a mean - spirited teacher, so it's hard for him to accept Snape as a guardian right away. Also, Snape has to protect Harry from the threats of the wizarding world, such as Voldemort's followers. He has to constantly be on guard and anticipate any potential attacks. Another challenge is dealing with Harry's friends. They might be suspicious of Snape too, which could create problems when Snape is trying to keep Harry safe and make decisions for him.
One challenge could be not being able to change things as easily as he thinks. Time might have its own rules. Another is that he might accidentally change something that has a much worse consequence later.
One challenge could be the lack of Muggle - style technology knowledge. Harry is from the wizarding world and might not be familiar with the complex electronics and coding that are typically part of AI development. Another issue could be the magical interference. Magic and technology don't always mix well in the Harry Potter universe, so his spells might disrupt the normal functioning of the AI components.
One big challenge could be Snape's natural inclination towards the Dark Arts. Harry would have to constantly keep an eye on Snape and try to steer him away from that path. Also, Snape's personality is often prickly and guarded. Harry would need to break through those barriers to really connect with him. Another challenge might be the expectations of the wizarding community. People might not understand why Harry is raising Snape and could be suspicious or judgmental.
One challenge could be dealing with magical laws and regulations regarding land ownership. There might be restrictions on who can own certain types of magical land, or special permits required.
