Fantasy

What would you feel if the last remaining happiness in your life—your cute, clingy dear sister—was murdered right before your eyes by a few worthless scum? By some bastards who shouldn't even exist in this world?
    I felt rage. Hatred. At them
    But more than that… I hated myself.
    Truly.
    Why?
    Because I couldn’t move.
    Paralyzed from the neck down, I could only watch as she died, as her blood spurted on me.
    I couldn’t scream. I couldn’t fight. I couldn’t even crawl to her, while her eyes were turning dull.
    Ah~ now they turned to me. Guess they are going to kill me too.
    But I don't want to die, at least not when they are alive.
    I've learned something in this time.
    In this apocalypse... weakness is a sin.
    The greatest sin.
    Here, no rights protect you. Not like they protected us before the apocalypse.
    No one comes to help you. Friends, neighbours, relatives.
    NONE.
    Strength.
    Personal strength is the only authority that truly matters in this new world.
    And,
    If you think this is where my story ends—you’re wrong.
    Because,
    [Regression possible: Yes/No?]
    Guess this is my cheat.
    I will return. Stronger than before.
    And I will DEVOUR everything that stands in my way.
    So then… sayonara, readers.
    “Yes, I accept.”

    This is my first novel, so it probably won’t be perfect—but I’ll keep getting better as I write.
    Give your reviews on this so I can improve where I have to.
    [Note: The story will be slow paced and I'll take my time to give all the characters their time to blend into the story.]
    [Note: There won't be R18 stuff from the start, so don't come here expecting hot scenes from the first chapter. It will take some time before I focus on that.]
    [Most Important Note: There will be yanderes. Lots of them.]
