My Black Impermanence Uniform: My Little Sister Stole It

The world is overrun by ghosts and monsters, and humanity is on the brink of ruin.

Gu Jinran transmigrated here and awakened the Underworld System. With his own power, he established the Underworld and commanded billions of ghosts.

Unfortunately, he accidentally left Black Impermanence's ghost robe at home one day.

His younger sister, Gu Meng, happened to take it for a cosplay outfit and wear it to the school festival.

And then...

Evil spirits ran amok during the festival!

The Black Impermanence robe worn by his sister, Gu Meng, came alive!

"Peace throughout the land!"

"Impermanence claims lives, and ten thousand ghosts snatch souls!"

"I am Black Impermanence. By my command, the guilty shall not be spared!"
