So much punch packed in one single episode!
21 December 2015 | by chandler_joeySee all my reviews

I am a sucker for endings done right. And this series hands down beats all recent anime endings I have watched. Why? Because it makes you want more but also leaves you with a funny closure, Saitama back to one punch victories.

The series has been so detailed about Saitama powers and yet not revealing the story behind it. Like when he is thrown to moon and he throws a stone just to see how much power it will be required to go back to earth without destroying the moon. Just amazing.

It's killing me not knowing how this god came into being. Though we finally get to see (one of?) his ultimate move, the SERIOUS PUNCH. You can imagine the fight if you know he had to use this move.

It's also killing me that no one other than Genos knows Saitama's true power. But I think that's what a strongest hero is. It's not the kind of person who boasts and goes mad across the galaxy to find a match for himself (Lord Boros) or even someone who without participating calls others weak (Amai Masuku) or even the powerful telekinesis who is too full of herself (Tatsumaki) but a person who even after defeating his enemy with one move appreciates the battle they had. I think it's this humble, just want to find the right enemy type of hero that this title is so apt for. And I can't wait for Genos to learn the same from the best sensei he could have found.

This season was perfect set up stage for saitama, hero's association, character development for heroes and mystery around each one of them. In love with one punch man.
