After watching both seasons, I would say this is one of the best isekai anime out there with awesome story and character. So many things to love it for but most importantly the message it conveys. I won't explain it tho as it's up to you to decode it the way you want.
There are so many isekai anime with overpowered protagonist that it becomes cliche. But this shows that it can be even harder to live in an isekai world if you're a human. Even deadly. The pain, the sufferings and the gore are just right.
The best thing is the anime is not rushed. It is at the right pace to build up the story and shows us the important bits. New characters are more interesting and everyone has a good backstory to support their character.
All I want to say that that this gets me hyped up for the next season and all the new adventures and character that comes along with it.
Thanks, Tappei.
