Everyday Life with My Saintly Big Sister After I Became a Demon God

My name is Su Yu.

I don't know when it started, but I realized that it felt as if I'd never managed to succeed at anything in my life.

My parents died when I was little, leaving only my sister and me. Then, when I was just seven or eight, my sister suddenly disappeared too. In the end, my neighbor raised me.

My school years passed just as quietly and without notice. Then I "proved" myself in the college entrance exams, successfully becoming unemployed.

As for my career, nobody wanted me for any job, so I could only stay home and write novels. In the end, I accomplished nothing...

Then one day, after returning empty-handed from a disastrous meeting with a publishing house, I was hit by a car while crossing the road...

A girl who calls herself a demon god, a sister who suddenly returns, and a life that's getting more and more ridiculous...

"W-what on earth is going on?!"

(A life that's supposed to be ordinary, but isn't ordinary at all!)
