When the Paranormal Invaded, My Sister and I Had Only Each Other

[Eerie Invasion] + [One Female Lead] + [Thriller] + [Heartbreaking]

Grandma said the sun used to be golden, and blankets dried in its warmth smelled lovely. I've lived for ten years and never seen a sun like that. The night the blood moon appeared, the sky turned red. Ever since, the sun has never been warm again. It hangs there, pale and wan, its edges faintly tinged red, like a half-open eye. A light red fog hangs in the air all year round, and two-thirds of the population has already been infected. They eat, talk, and laugh as usual, calling you home, until something inside them wakes up and stretches a mouth that isn't human across your face. Chen Chen is an orphan taken in by the Chen family. His only family is his sister, Chen Nuan, who is ten years older than him.

Chen Nuan is a trainee ghost slayer with the Ghost-Slaying Alliance. She awakened the A+ rank ability “Everlasting Light,” which uses her own life force as fuel to heal, protect, and hold on to everything she doesn't want to lose. Each use leaves her with less life. She never says a word about it.

A three-day visit home was Chen Nuan's last.

On the first night, Grandma's mouth split open in the moonlight. At dusk on the second day, Grandpa, who had lain dormant for twenty years, bared his claws and fangs. Amid the blood and moonlight, Chen Chen awakened the S-rank ability “Return to the Void,” which turns his body into a vessel that devours all energy. The more he absorbs, the less human he becomes.

Grandma was gone. Grandpa was gone too. Their home was gone.

Chen Nuan led him out of the village and into the Ghost-Slaying Alliance. From then on, they had only each other.

She led the way, cutting a path with her blade; he followed behind, using his body as a shield.
