In hopes of escaping the world, Iris resorted to suicide to be her answer. Succeeding, she finds herself in the middle, or the 'gray' of life and death. Being trapped on Earth, she experiences her short life of fifteen years over again in brutal clarity. Tackling life, death, happiness, betrayal, heaven and hell, Iris and a deceased classmate live in the areas of death.
With 'holy' blood on her hands, vengeance has become even more immoral than that of the original target. Thus proving nothing ever truly ends, but only begins.
You know that feeling when you feel like you want to kill yourself? Not out of sadness, but out of hatred? That's the feeling that I've felt my entire life. Everyday, when you look at the clock and you just see the seconds hand slowly move around the clock. When it'd just stop raining and you see the raindrops fall slowly off the wall. Sometimes when you're just sitting in class and you blur the whole world out and think. The life of every high schooler. Sometimes the world is just so terrible and annoying, you have no other idea than just to commit suicide.
