Sirius Black ran away from home at the age of 16 and went to James Potter's house, where Sirius ran away from home in conflict with his parents' pure-blood firsts. Jaime's parents treated him very well, like the second son of the Potter family. This was unanimously opposed by the Black family, especially his mother, and Sirius Black was removed from the family tree, and around 1979, after leaving school and getting rid of the pure-blooded family, James Potter and Lily Evans entered the marriage hall with Sirius Black as the best man, and Sirius and the other three Marauders became members of the Order of the Phoenix, founded by Dumbledore.

His position within the Order is unknown even to Kachel, who has read the original books in his previous life, but before Harry fans in his previous life discovered that a spy had passed information on the Death Eaters, everyone unanimously speculated that he must be an activist. Lupin is suspected because he is a werewolf, and Sirius is suspected because he was born into an ancient dark magic family. However, Jaime never doubted Sirius, and he maintained his friendship with Sirius, making him the godfather of his children, and making Sirius their secret when the couple hid and cast the Curse of Courageous Loyalty.

When Harry Potter was born in 1980, Sirius Black became his godfather, and if anything happened to the Potters, a danger faced by members of the Order of the Phoenix, more than twenty of whom gave their lives on that terrible day, he would become Harry Potter's legal guardian. On the surface, Sirius Black was the Potters' secret, but in the second year of Sirius' becoming the Potters, Sirius and the Potters discussed and replaced the secrets with Peter Pettigrew, who he thought was reliable, and Peter betrayed the Potters and told Voldemort the hiding place of the Potters and Harry Jr., leaving Harry an orphan.

When Sirius Black saw that Pettigrew was the most anomalous, and found that he had moved away from his original residence, it didn't feel right. So he rode his flying motorcycle to Godric's Hollow, where only the ruins of the house remained. Hagrid saw him there, and later caused a misunderstanding that Sirius divulged the secret. Sirius Black believed that as Harry's godfather, he was supposed to exercise custody, but Hagrid insisted on taking the child to the Privet Path as Dumbledore had instructed. Sirius Black lent Hagrid his favorite flying motorcycle.

After such a betrayal, Sirius captures Pettigrew, who once again manages to escape, killing a street Muggle, cutting off his own fingers (for which he later received the Order of Merlin of the First Degree) and pretending to be dead himself, the only achievement he has not been overshadowed by Sirius. Sirius (who even his best friends thought he was a secretie, and he was the only one who could betray the Jaimes) was arrested as a murderer and spent 12 years in Azkaban, where everyone believed him to be a traitor and a servant of Voldemort. Peter screams that Sirius Black killed Jaime and Lily, and then causes a massive explosion. Sirius Black is identified as the killer of the Potters and is sent directly to Azkaban without trial.

Sirius Black didn't go crazy because he was soberly aware of his innocence. In 1993, when Cornelius Fudge visited Azkaban, Sirius Black asked for a newspaper, and he came across an article in the Daily Prophet about the Weasleys' trip to Egypt — with a picture of the Weasley's family and a mouse missing a toe. Sirius had seen him transform countless times, and he knew exactly who it was: it wasn't Ron's pet spot, it was Peter Pettigrew. He's still alive, he himself cut off one of his fingers, Sirius vows to catch Peter and kill him, Peter hides in the Weasley house for 12 years, being a pet for 12 years. Sirius escaped Azkaban and went to Hogwarts. He realized that Harry's life would be in danger wherever Wormtail was. Sirius Black managed to transform into a dog, and then, one night, slipped past his guards and swam back to the mainland, until now Sirius Black escaped from Azkaban and ended up here Hogsmeade!

It's really sad for Carchel to think about these Sirius in his life, but Carchel doesn't want to change anything, because, Carchel knows that he will definitely fall out with Dumbledore, the old guy, if he saves Sirius, then this is completely for the sake of the enemy, and Carchel will not do anything like that!

Sirius Black saw Dumbledore put down his wand and said; "Oh, Professor Dumbledore, long time no see, are you trying to get me back? You should know that I am innocent! Moreover, Peter Pettigrew, the Pettigrew, who really betrayed James and Lily, is now in Hogwarts, and I must find him, and then, torture him until death! Sirius Black said with a hideous face, and became excited as he spoke!

Dumbledore had no expression on his face, and he had always had a faint smile on his face; "Oh, Blake, of course I know you're innocent, I'm sorry, I can't do anything for you at the beginning, and I know you hate Peter Pettigrew, but I do have something to do with you now!" Sirius Black's original angry and struggling face heard Dumbledore say this, and slowly relaxed, and at the end, returned to calm, Sirius Black said lightly; "Professor Dumbledore, as an important fugitive I'm chasing after the Ministry of Magic, I don't think I'll be able to help you with anything!" Dumbledore heard Sirius say this, and hurriedly shook his head and said; "No, no, Blake, this matter can get you away from the charges of being a fugitive from Azkaban, and even clear you, of course it's not mine, it's him!" Dumbledore said and pointed at Cachel behind him with his slender and somewhat wrinkled fingers!
