At first, when Harry uses Edo Tensei, there would be chaos. The resurrected wizards would cause a stir in the wizarding community. Some might be feared, others might be revered. Harry would have to deal with the reactions of his friends and foes alike. He would also have to figure out how to control the resurrected ones and what to do with them in the long run. As the story progresses, he could use them to gain knowledge about old magic or to fight against Voldemort - like enemies. And he'd constantly be in a moral dilemma about whether he's doing the right thing.
The story could start with Harry discovering the knowledge of Edo Tensei. Maybe he stumbles upon an ancient text during one of his adventures in the restricted section of the Hogwarts library. Then, he might initially be hesitant to use it but as the threat in the wizarding world grows, he decides to give it a try.
In this kind of fanfiction, the story's progression might depend a lot on the purpose for which Harry uses Edo Tensei. If he uses it to bring back his parents, for example, their presence could change the entire dynamic of his life at Hogwarts and in the wizarding world. They could offer him advice, protection, and new magical knowledge. However, the wizarding world might view their resurrection as a dangerous precedent. This could lead to a conflict between Harry and the Ministry of Magic, with Harry having to prove that his intentions are good while also dealing with the consequences of bringing the dead back to life.
