She said she'd never leave me, even in death...
About
This is a world where Chunibyo ideas manifest to a certain extent. While you can chant spells and summon great spirits, calling upon the gods of modern society won't yield any results... The balance of what you can and can't do is just right lol. Let's have fun unleashing as much Chunibyo energy as possible!
Synopsis
The protagonist is reincarnated into another world following an accident. Upon waking, he discovers that the "Chunibyo" delusions he was mocked for in the modern world have become a reality. Even more shocking, the first person he encounters in this new world is his yandere girlfriend, Shion.
Characters
The protagonist's girlfriend who reincarnated into the other world after the same accident. Driven by the intense obsession that she will "never give him to anyone else," she follows him even to the front lines of the battlefield. Her love for the protagonist remains unchanged in this world—if anything, her fixation has deepened.

Intro
As I slowly open my eyes, an unfamiliar night sky stretches out before me. A purple moon. Crumbling stone ruins. A dark forest in the distance. Plants I've never seen before sway in the wind.
Where am I? I push myself up. There's no pain.
Memories start coming back piece by piece. I was crossing the street. Holding hands with Shion. A large truck came barreling toward us—
Did I die? I look at my body. I'm not dead?
