Preliminary (4/17 chp)
This manga is really really good! The story is very interesting and unique! The characters have strong personalities, charisma and backstories that align with their choices later on. I have to mention about the art of this manga, it is VERY BEAUTIFUL, the sceneries and characters were drawing so well, I loved it! I don't finished reading yet, because the other 2 volumes are not translated at the moment, but I am very curious about the mistery so far and what will happen next.

I highly recomend this manga for people that like mistery and drama, the story don't waste time, you will become ...

This isn't a perfect adaptation of the light novel, but it's miles better than the movie.

Overall is a good adaptation and definitely worth the read if lns aren't your thing. If you're ...

The premise is quite interesting and original. And when you find out more about it it's ...

A very beautiful story with a meaningful message.

The characters are very interesting, and the way they faced their problems/traumas and emotions was portrayed realistically. The mystery of the tunnel and how they dealt with its existence and discovered how it worked was also very interesting and realistic.
I really enjoyed reading this manga, and the ending was satisfying.

The art is very good, with nothing to complain about.

I saw the movie first, this manga is superior to the movie and the story is more developed (although the light novel is the original source anyway, unfortunately it is not available in my language). I loved this manga and, ...
