To save his seriously ill sister, college student Noir Chaucer buys a haunted house for a hundred bucks, unexpectedly activating the "Negative Emotion System". The more terrifying the ghosts become, the stronger he gets! This ignites a series of unconventional tactics, as he outsmarts and tames all sorts of supernatural entities: the gentle maid Rose, the resentful child Bobby, the fox spirit maid Ivana Hammer. While others rely on spells to banish ghosts, he drives them mad with his words! The haunted house turns into a paradise, ghosts and monsters become family, and the hilarious journey of exorcism is awesome!
