The five poisons ( The promised neverland)

It has many years after Emma and her family escaped the demon world. And somehow Emma managed to gain back her memories, but then however both her, Ray, Norman, and the rest of her friends and family were then transported to an unknown dark place that was when they met all of their previous family and friends that were dead.
And somehow they both met Musica and Sonju, and although they were happy at first, they began to ask questions about what was going on when they suddenly met a human in his late twenties who then introduce himself and then gave both Emma and Musica a journal and then they were transported back to their regular worlds.
And when they look at the journal and began reading it, they suddenly realize that they are reading one of the previous child cattle that has managed to escape the demon world without doing the promise. And these people were known as the five poison.
