Rules for a Mute Guardian Spirit

Tsushima Ringo has always known that trust between people is fragile. At the same time, though, she believed there was one person who would never betray her.

Until one day, she was betrayed.

She began plotting a vicious, unforgettable revenge.

And she succeeded.

Our blood binds us. I curse you.

This is the cursed spirit storyline in the main world of the author's other work, "After Being Hit by a Book, the Tool Character Decides to Save the World." Updates and crossovers are whenever I feel like it ( ), though you should still be able to follow this without reading the other story ( ).

Since the characters have different experiences here, their personalities may differ slightly from those in the other story.
