My name is Midou Sayaka.
I'm a very normal third year high school student, I think...
But whenever I ask my friends "I'm normal right?" They all shake their heads at once.

My grades are very normal.
My looks and height are probably average... I think.
The fortunes I get are always bad.
It's always raining when I go on a trip.
People that I like always end up liking one of my friends instead.

...I might be a little unlucky.

However, I'm always lively, Today I safely arrived at my graduation ceremony.
The university I wanted to go to didn't accept me, but Mom and Dad said it's OK to be free for a year.
From tomorrow I have to study hard!
Even though I may be unlucky, I'm happy.

I never imagined that I might get caught up in an event that would endanger my life.
An oni and a technique user, as well as a killer. Even in a dream I never thought I could be connected with these kinds of people.

In order to live you need to hate, the Oni said.
You will hate if the people important to you are lost, the Technique User said.

In order to protect the people important to me, what should I do...?
