Subaru is, of course, the main character. His ability to return by death drives the whole plot. He is a complex character who grows throughout the story. Beatrice is another important one. She guards a library and has her own unique powers and personality. Her interactions with Subaru add a lot to the story. Roswaal, a powerful magician, also plays a significant role in the political and magical aspects of the story.
The theme of sacrifice is also there. Subaru often has to make sacrifices, whether it's his own well - being or relationships, in order to achieve certain goals. And the exploration of the nature of time and causality is interesting too. His resets affect not only his own actions but also the events and reactions of other characters in the story.
