I applaud for the amazing animation that's been effortlessly stunning in its backgrounds. However I thought this anime's story was near to jump off the edge because it was really slow and its characters didn't seem that interesting to me. In fact they were confusing and a bit annoying because I couldn't tell what they were at in the "outside" world although all I knew was that the characters were escaping from the orphanage...Not the best anime I've seen but major improvements in regard to character and storyline development could've made me give a big fat 8 or 9 rating. However I'm going to give this a 4/10!

This anime starts off as a semi-compelling story about a young girl that want to explore a cave system known as The Abyss. During one exploration day she finds a boy who looks human but isn't. She names him Reg and together the go on an adventure to discover the abyss. So far so good, it it's a story with a mystery and lots of lore. It is drawn in a cute style and lulles you in to a false sense of security thinking that nothing bad can happen in an anime this adorable. But you would be so wrong to think that. The deeper our main characters go in the abyss, the darker the show gets. Up to the finale where you feel utterly disguited by what humans can do to others. A very interesting anime clearly made for adults, this is nothing you leave on for your kids, and I strongly urge people to keep a close look at the recomended guidelines for viewing.The main bother about this anime is that it is slow as dirt. Many of the episodes recap big chunks of the previous episode. Given that an episode is about 20 minutes, wasting 5 or more of those on recaps looses you 25% or more of the runtime. At first I thoughts this was done to pad the runtime in lack of substance to fill 13 episodes, but the show finales without an ending and with more unsolved plotlines than solved ones.

This show went from one I was intending to skip to my favorite this season. When you look at the initial picture for the anime it looks like it is made for children due to the art style.After hearing that this is not a kids show I thought that I'd give it a try and it really is an interesting even though sometimes cruel anime where especially at the end of this seasons you might want to have some tissue in range to wipe away tears.The premise is that there is an abyss on a specific island and adventurers will go into the abyss to get treasure. It sounds like a typical dungeon crawler show at first glance. However there is a twist. The deeper you go, the harder it will hit your body when you return to the higher layers and town. It starts with possibly throwing up and goes till death/loss of once humanity. For the latter there are no specifics what this exactly means.So you go in and could get great loot, but the price might be your live.The story centers around a young girl that enters the abyss with a specific goal in mind and is accompanied by robot that also looks like a kid and was coming from the Abyss.We have a slow start that introduces the main as well as various other characters and hints on what happens with you in the abyss. Halfway through the show it will pick up though and is not suited for children at all anymore. There is a lot of mental and physical pain put on the characters and we always have to remind ourselves that these two behave like and are children. So for some this will be hard to watch.In addition it will show the painful results of injuries and doesn't hide anything. Still the show manages to put in lighter moments with humor as well.It is overall well written and I think the pacing of the show is fine even with the slow start, because when it goes dark it hits you even harder with it.I'd highly recommend it. However I give it an 8/10 because the story is unfinished and I'd preferred the art style to be a bit more adult. If you like the art style overall you could take it as a 9/10.Btw. the soundtrack for this show is amazing.

At first glance, this anime seems childish and just cute, but it's far from it. From episode number one, it throws the viewer into a deep dive in a complex universe that has its mythology as well as many mysteries. The story has as many layers as the abyss, with the main characters fighting odd creatures and having major character developments in the process. And as they get deeper into the abyss, the darker the anime goes. And the more depressing as well. In the end, there were many questions answered, so hopefully there will be another season.
