The Time I Became a Ghost in Someone Else's Nightmares

Supernatural Horror Means Supernatural Horror. Don't Drag in Rule-Based Horror or the Dreadful World

Looking for Something Like My House of Horrors

The protagonist can heal and help otherworldly creatures, reach their hearts, and has an optimistic, positive outlook.

Looking for a Good-Hearted Protagonist in a Supernatural Horror World Who's Powerful and Helps Ordinary People

The protagonist shouldn't be cold-blooded or a show-off. They should be a good person who saves ordinary people and has compassion! The side characters should be smart, too. Preferably no female lead! I hate ruthless protagonists who have power but still send ordinary people to their deaths. And no show-off protagonists either!!!

Ancient-Era Supernatural Mystery: Hunting Ghosts and Leveling Up

The protagonist transmigrates to ancient times, where ghosts and monsters run rampant. There is an exorcist guard or something similar established by the imperial court, and the protagonist kills ghosts to level up.
