Episodes 1 and 2 are a great introduction if you're new to the series, showing all of the major characters along with their personalities and interactions.
Episodes 3 and 4 introduce two new characters and their interactions are just in general very funny ^^
On episode 5 we see the start of the Industrial Revolution Arc, and Arthur being a tsundere as always! Episode 6 got me to ship something I'd never thought of before, so that was great.
My favorite so far is definitely episode 7 though. I could not stop smiling throughout the whole thing, Ivan and Raivis were just both so cute! <3
As of when I'm posting this, episode 8 was the last one released, and I also really love it. I move so fast as soon as I find out that a new episode is out! I look forward to it every week!
All in all, great art style mostly kept over from beautiful world, great story and humor as is customary for the series, but it's even better in this season than any other! World Stars made me fall in love with every character all over again. 10/10 Would recommend.
For those who hate Hetalia, I suggest you put your opinion on the fandom and the "cringy fangirls" aside and give it at least a shot, because it's really funny and historically accurate.
