I Became a Ruined Character in a Dark Fantasy - Chapter 30

Based on the popular Vocaloid series, by HoneyWorks, called “Kokuhoku Yokou Renshuu (Confession Rehearsal)“:

Natsuki, a third-year at Sakuragaoka High School, who holds unrequited feelings for her childhood friend, Yuu, who’s in the Film Club. However, instead of being honest about her feelings, she makes him be her confession “rehearsal” partner. Unable to say her true feelings, things start to get complicated when Miou and Akari, who are also in the Art Club, get involved! Will she ever be able to confess for real!?

The female protagonist of this book is a zombie (probably!) The male protagonist of this book is an air (maybe, but you can’t see it?) The system of this book is a bastard (like to open a mouth too much?) Anyway, this is a story about zombie with a memory, going back to the past, but accidentally turning this book into a story of a savior! (Huh? What? There is a killer? No, believe the author, she really did not kill, really! (No wonder!)

The heroine said: The title of the book and so on are all fake!

Year 24XX. With several hundred years of improvements, virtual reality has become more mature. It had gradually become humanity’s second world. Socializing, working, studying and other everyday things could all be done while sleeping.

It begins on the mountain.

With the glint of a knife, a flash of steel in the hands of a sworn brother. A betrayal.

Stabbed and pushed down the mountain, Zi Chen lied within the red-stained snow, left to die.

This is where it begins; he is given life by lightning,
baptized by thunder.

Those who had once betrayed him should all suffer in his cruel revenge.
