Terrified of the Deep: My Yandere Sister Begged Me Not to Kill Her From the Start

After transmigrating into a horror game filled with elements like grotesque creatures, Lovecraftian themes, punk aesthetics, healing moments, beautiful girls, and costume changes, I almost mistakenly killed the sister-type heroine right at the start. Since the game is Lovecraftian in style, despair is the only possible ending. To survive longer, I decided to uncover the hidden happy ending route! But over time, just getting a so-called “perfect ending” wasn’t enough for me anymore. In this world where void and existence overlap, where humanity is distorted and fate is warped, and where truth and lies constantly switch places… I’ve decided—I want to become the greatest horror in this world! “But, dear sister… why did you become an eldritch god before I did?”
