*TL;DR at the bottom alongside an author's note*

I remember seeing the announcement for the anime of this... I would never have thought that this would become one of my favorite manga of all time, rivaling my love for Jojo, Berserk, and Oyasumi Punpun on their own. Also inspiring me to change my profile picture to that of Riko eating an onigiri.

It's a story filled with just raw emotion which pops out thanks to the incredible art, especially in the most recent chapters that have been released in English and/or Spanish (since I also speak that language).
There's also this best dad guy. The things he does are so utterly lovable, it made me love a fictional character to the point I wanted to just shout compliments to him and his motives... It might just be me though.

Another thing this manga does really well is the feeling of dread the abyss creates just with its presence. The reasons why? The "curse of the abyss", the creatures, the people residing in it (like the one mentioned before), and just the abyss itself with its layers of mystery, making you guess what might be at the bottom, what other creatures inhabit it, and just who could be the next person our protagonists might encounter.

And then there's the characters: I've never rooted for a bunch of kids to succeed to this level in a long while. Every time they are in peril or in a tough situation I just find myself sweating and my heart beating fast.
The villains and the not-so villains are also really great.
There are only a few characters I found myself not really hooked with as much, and they are the other kids at the orphanage (except for the toddler whose name I forgot). They aren't as developed, but I still like them.

I really couldn't stop reading this manga as soon as I started, too. That feeling of just "one more chapter" is fantastic, and the anime managed that wonderfully too.
One last thing though: I really can't recommend it to everyone, due to all the dark and gory moments. Also the fact it has nudity. Read it with caution.

TL;DR: Made in Abyss is a manga filled with emotion, great characters, a mysterious world, and you might just won't stop reading it. Only read it if you aren't so bothered by gore, kids suffering, and child nudity, to the point where you might just drop it.

Author's note: This was my first review. Been almost three years on this site, and finally decided to make a review. That should probably tell you how much I love this manga.
