Izumi Toma is a firm materialist, though his life changed a little after he accidentally fell off a cliff and met a black bird that insisted on feeding him meat.
What do you mean, "Auntie Next Door's Springtime Crush: Young Man, Come Knock on My Door," "The Transfer Student Whose Motto Is 'Sumimasen' and His Cursed Little Sister," "After I Turned Down the Beautiful Girl in My Class, She Shouted and Grew Another Head on the Spot," "I Don't Believe in Superpowers, but the Boy in My Club Really Did Turn into Light and Fly Away," "Those Years I Spent Disciplining My Rebellious Country Cousin Who Had a Mouthful of Nails," "A Balloon the Size of My Face Suddenly Appeared in the Sky. Who Loves Me This Deeply?" and "A Thousand Layers of Superstition: The Rumor About a Handsome Young Man in Black at the Crossroads Is Trying to Lure Everyone into Staying Up Late to Tell Fortunes"...?
Science doesn't seem able to explain these things anymore, but life still has to go on. Izumi Toma decides to ignore the strange happenings and carry on as usual.
That is, until the strange things stop terrifying him and start confessing their love to him.
Izumi Toma: I'm really scared now. I've had enough, okay? I'm out of here.
Niko: So you're the guy who turned the characters I wrote into lovesick fools?
Important notes:
1. A wish-fulfillment, brainless harem romance written to satisfy the author's tastes. It's normal for people, ghosts, and monsters to inexplicably fall for the protagonist. Readers looking for the logic of a serious horror manga should steer clear.
2. Some female characters from the original works are gender-swapped, such as those from Group Ward and The Circus Has Come.
Theme: The possibility of becoming a harem protagonist in an abnormal world.
