Reality Invasion: My Girlfriend Discovers My Demon Back from the Start?

The world changed.

Demons, monsters, the supernatural, and creatures from anime and novels all began appearing in the real world.

Then, while I was testing my strength, my girlfriend suddenly barged in. It seemed like she saw the secret on my back. What should I do? Asking online!

Demon Back: The ultimate ** hiding ancient power!

Heart Engine: Constantly produces blood to speed up recovery!

Demon Brain: Simulates opponents, letting me use the simulations of my enemies!

Demons are terrifying, but even more terrifying is the ghost face on my back.

Emile: "Explain yourself! What was that on your back just now!? Why didn't you have it in your previous life!?"

"And what does 'ghost critique' mean!!"

Jiang Ran: "???"

Demons: "Which one of us is the ghost, you or me!?"

The supernatural: "Behind that man is the devil!"

The monsters: "Don't come any closer!!"
