I thought I'd make a new thread on this anime because I don't think it has been mentioned in any previous threads (to my knowledge, apologies if it has) and I think it deserves one.
I've recently just finished watching this anime and I thoroughly enjoyed it!
It's absolutely hilarious with a crazy/pervy theme to it and the characters are awesome.
There are some more serious/emotional episodes as well which are done fantastically.
The entire series (seasons 1 & 2) can be watched straight from YouTube at:

I'm hoping they get enough support and make a season 3.
