Reiwa no Dara-san

Sinopsis

Clouds blacken the sky and sheets of rain turn the mountain forest into a treacherous maze... A landslide crushes a razor wire fence, and buries a "NO TRESPASSING" sign... Two young siblings wander into a dark world where they do not belong, and a long, horrid shadow rears up to meet them—Anyway, so that's how we met Dara-san! She might look kinda scary, but just wait until you get to know her! "Look, I'm a god of misfortune, okay!? Aren't you kids gonna freak out about my grotesque visage!?" (Source: Yen Press)
