I'm not entirely sure as I haven't read it in detail. But generally, it might continue the story of the Bleach universe, perhaps resolving some loose ends from the main series.
I assume the main characters would be the ones from the original Bleach series like Ichigo Kurosaki. He was the central figure in the anime and manga, so it's likely he plays an important role in the novel as well.
The last chapter of the novel was chapter 253, which was the last chapter of the fourth volume of the novel. In the final battle, the Qing Emperor, Fan Xian, Wu Zhu, and the others engaged in a fierce battle. After the Qing Emperor was injured by Fan Ruoruo's sniper rifle, Fan Xian took the opportunity to sneak attack the Qing Emperor and eventually killed him. The Qing Emperor's death was an ending he deserved.
