I was originally an NPC.
One day I suddenly woke up and I met some people along the way.
With my hard work, I also became a heroine, but I became confused.
What is the so-called real world like?
Many people like me are looking for [Codename 0], who is said to know everything.
After traveling through one world after another, I feel closer and closer to the answer I want...
Idea: NPC can also become the protagonist through hard work.
