I was gonna write a prediction blog but I haven't got the time so here's what I think will happen next chapter.

The battle resumes, with Nemu in the fray this time. Pernida begins overwhelming them with arrows, and Mayuri begins having a flashback when he sees Nemu with a look of regret on his face.

Hundreds of years ago, Mayuri is a Shinigami wavering through one of the districts to collect specimens for an experiment. He thinks he is alone when suddenly he hears someone crying in the distance. He looks and sees a baby. At first he thinks not my problem and walks away, but the baby cries again and Mayuri feels a twinge. Attempting to hide it he says, Well I do need a lab partner and picks the baby up, naming her Nemuri.

As Nemuri grows, she assists Mayuri in his experiments, and the two form a close bond. One day, Nemuri is kidnapped by people attempting to get their hands on one of Mayuri's experiments. They tell Mayuri that only if he gives it to them will they let her go free. So Mayuri brings the experiment to them in one of the districts, but they pin him down, take it, and kill Nemuri. Before they can kill Mayuri, he flies into a rage and uses every tool at his disposal to murder everyone in the district, to make them suffer. He succeeds, but wiping out an entire district is not looked on kindly by the Central 46, and Mayuri is sent to prison for life. However, after Kisuke frees him, Mayuri gets to work on bringing Nemuri back. After six failed attempts, he succeeds, though he knows that she will never be the true Nemuri.

Back in the present, Pernida manages to injure Nemu and she and Mayuri are severely threatened. Suddenly, a shot blasts through Pernida's palm. In comes Kisuke, saying Now now Mayuri, don't go running off like that!
