Why do you like minori so much, she's awful. She literally tried to make mob kill his cat :/
Minori was being possessed by an evil spirit. Although we do know that she was a bratty girl and possibly bullied kids before Mogami, we are shown that Mogami made everyone in his universe about 10x more evil than they actual are just to torture Mob. During the events of the Mogami arc and in the Mogamiverse, Mogami is basically controlling the way Minori acts to make her more evil, twisting her mind to make her a borderline murderous person. Minori is nothing but a pawn in Mogamis hands, a puppet to use to torture Mob and make his life a living hell. We’re not even sure how conscious she was during most of the time in the Mogamiverse, seeing as she claimed to have forgotten most of what had happened.
She was a possessed 14 year old with almost no control over her own actions in the Mogami arc. She apologized and is visibly disgusted and upset with her own actions.
If Mob believes that she can change, I think we should believe in her too.
