The premise is straight forward and smells like slop, meaning a cynically pumped out show with little to no variation.
I can't claim that it meaningfully deviates from formulaic isekai-like generic fantasies, because it relies on too many tropes and never feels like a full throated production that people put their passion into, it looks fine, the acting is fine, the music is fine and while none of it is special, it also never disappoints.
It's a very decent story that has an appreciably slow pace without dragging things out or getting stuck in exposition. The people behind it may not have given it their all, but they did care about making this.
The premise is simple, you take your average fantasy world with a guild system and adventurers in it and resurrect the main character from being a middle-of-the-road adventurer who never got anywhere as age starts to creep up on him, to getting eaten by an impressive looking monster, inside of a labyrinth, and dying.
Whether he's spit out or comes out the other end, the end result is the same, all that's left of him are bones. And he's still alive, as a 'monster'.
The dilemma is that he can't just go outside the labyrinth or he'll be slain by adventurers or guards. The hook, however, is that he is now stronger than he used to be and experiences a natural talent for combat and physical activities that he didn't possess before.
What's more is that when he slays monsters he rapidly becomes stronger and even evolves (basically getting XP and leveling up).
This is important because his dream is to become a 'Mithril ranked adventurer' and finally sees a shot at progressing towards it.
Our main character is mild mannered, pragmatic, kind and principled, he's well liked and people think of and care about him.
It's also refreshing that he thinks about things like an adult and isn't a screaming and hot headed shounen protagonist.
While the story quickly solves his issue of appearance, it just as quickly deviates from that as the active plot, however it does keep it in mind to some degree as he's forced to interact with others in order to be an adventurer, even if he's solo.
The reason I enjoy it so much is that most of the time it feels like an actual adventure and that his relations to others feel largely natural. He has a close friend whom he can discuss his situation with and talk and think about how to deal with his situation and what he actually wants to do.
Not a show I actively look forward to, but I'm happy every time I see it has an episode added to it.
