It is common knowledge that it is best to become an adventurer when you are as young as possible because the magical power that is the basis of an adventurer's strength will hardly grow if you don't train it while you are young. But this man, Rick Gladiator, who became an adventurer when he was over thirty years old, had the combat power of an S-rank adventurer, the highest rank in the world. In fact, Rick has lived an unimaginable life with the members of the legendary Orihalcon Fist, a party of the continent's strongest adventurers. From dragons to vampires, Rick's fighting prowess, trained by his literal "monster" mentors, allows him to defeat elite adventurers one after another who try to underestimate him.

I'm an elitist pig anime watcher, and while I act like I know something (and literally know nothing), there is one true aspect I'm an expert in - overpowered MC trash. Is this show generic? Yes. Is it stupid? Yes. Is it genuinely pretty good? In my opinion, 100%.

A big fan of the manga, the backstory of the main characters turn out to be great. Rick's party Orihalcon Fist is fun on screen, the waifus are cute, and the production is surprisingly good. While the world building and magic system is rehashed and generic, the self-aware humour keeps it a little fresh and the lovable ...

Anime Name is "The Ossan Newbie Adventurer, Trained to Death by the Most Powerful Party, Became Invincible"

This anime sounds generic but is one of the better ones. The story is about a character who trains hard with the strongest party and becomes invincible. At first, he pretends to be weak, which is explained by the third episode.

The main issue is the pacing. Fight scenes have too much talking, making them feel stretched. For example, a single fight can take a whole episode, which can get boring.

The animation is decent, better than some other fantasy animes but not top-notch. Some jokes and moments are ...

"This one is for the old Anime fans..."

The premise is relatively simple: a man in his 30s changes his role from receptionist at an adventurer's guild to hero.

He enlists the most potent adventures in the world to be trained, and even though he is past his prime, he is OP.

The anime Is one of those average animes that lack overall logic and depth; however, from a slapstick, nonsensical approach, it's not terrible.

I am watching many exciting anime seasons; this one is average to an extreme.

If you are pinched for time, I think there are much better animes to spend your time with ...
