Harry Potter: The Outstanding Graduate from Azkaban

After dying suddenly from overwork in the twenty-first century, Lu Yinan discovered she had transmigrated into the magical world of Harry Potter. But there was the gloomy cell, the mad cellmates, and the Dementors gliding back and forth. Could someone explain why getting into Hogwarts meant she first had to clear Azkaban? Irena: After dying suddenly, all I want is to lie flat, but some mysterious force keeps pushing me to work harder. Harry: Nana is the best sister in the world. Draco: Potter, why do you get such a wonderful sister? But she can only be your sister. The Weasley twins: Irena is an absolute genius at coming up with pranks. Snape: This school is full of trolls with their heads stuffed with Devil's Snare, except for Irena Nana, of course. Dumbledore: Is it really impossible for this world to produce a third Dark Lord?
