What I love about this novel:
1. It is beautifully written! The title is literally what the story is about, a girl who ate a grim reaper-like existence and is now immortal. The flow of the plot from battles to character development to inner thoughts is perfectly paced.

2. The complex characters have serious yet soft moments. Because the MC has a bit of a twisted character due to her childhood experiences, that doesn't stop her from cherishing her subordinates/friends. The relationship/loyalty between the MC and subordinates that develop over the courseof survival/battles is poignant yet tragic. The feels are real.

3. Because of how complex yet simple the MC is, it is easy to sympathize and understand the MC's train of thoughts. Since the story revolves a life-or-death atmosphere, the atmosphere goes from light to tense back and
The only issue I had with the novel is the ending. I found it a bit too open ended, so it felt unsatisfying. Overall, instead of going through a roller coaster, the story was more of a drop tower coaster type of feel. The build up moment was exciting and the drop down moment was just as exciting, but after everything is over, you're kind of left with a bittersweet feeling.
