All, more or less, new horror scenarios tied to part time jobs. That alone should make this manga pretty popular. There is some common ground, but in general there's a ton of creativity and variety in the types of life threatening supernatural threats our protagonists meet; while we slowly get to know more about them and why they are taking this well paying but dangerous jobs. The art is a bit stiff, you get used to it but if you pass over the pages looking for the creepy monsters you'll feel a bit underwhelmend by the general style. Nothing broken, just uninspired. But the money shotsare there, and even if they don't hit the concept behind them is more than solid enough to carry the horror aspect. Most of this could still work as campfire tales.

By far the strongest point is the creativity, and in something as saturated as japanese horror that means a lot. I'd recommend it to anyone who wants more of that genre and isn't expecting peak artistic quality.
