I recommend it if you're just looking for dopamine, but if you want an actual good anime, this ain't for you.
Plot is boring and predictable, abuses the shit old generic op mc with nothing to add other than the pseudo-isekai like mechanic that i wont spoil.
Literally only action and fights nothing else that really makes you want to watch it besides MC growth when you already know what's going to happen.
The animation is good, but the story is horrible. Another generic weird isekai-like to the bin.
I believe this anime is made for tourists and shonen"fans".
TL;DR: Watch if you don't care about story and plot.
