This story is (to my understanding) a prequel to a different story.
The origin of a new village which is close to an abandoned one with a disturbing past sounds really good!
The heavy use of advertisement to other stories got a chuckle out of me a couple of times, haha.
Also, the use of modified pictures to create a scene was honestly clever and beautiful.
SPOILERS BELOW
An issue for me is how everything is told to us.
The Main Character's backstory is narrated and the cast is also presented one after the other, but everything is told directly.
If this was presented in a more organic way, where we get to meet each character one at a time, and see how they interact between each other, it would help a lot with immersion and presentation.
This also happens with the abandoned Kirba village. We are only told about it, instead of it being presented as part of the story.
Maybe these things happened because of the time-limit, but in my opinion these points would enhance the story.
Overall, this has potential for a very good mystery or drama story
