Recommend "1 season animes" here

[ps3-sales!]

Yo

 

So I consider myself a pretty big anime fan. I mean for goodness sake I have my OWN ChrunchyRoll account. That's big time. 

 

But anyway, 2 animes that I've recently finished; K (K Project, 13 episodes) and Gargantia on the Vendurous Planet (also 13 episodes) really impressed me. Both sucked me into that universe with such a small amount of episodes. Plus I was able to binge watch them in a day or two because I obviously have no life. 

 

Got me thinkin', anybody know why other "1 season animes" that are good and they'd recommend? 

 

Edit: so it doesn't have to be exactly 13 episodes. It could be 5. Or 10. Or 25. Usually 25 would be a max though. 

 

By 1 season I mean the entire series concludes in 1 season. 

 

Series I've seen already: K, Gargantia, Fate Zero, Madoka Magica, Akame Ga Kill, Kill La Kill, Pokemon Orgins
