A very lightweight site to read manga on mobile?

My only way of using the internet for the moment is with my Playstation Vita. It has a pretty poor browser and can't handle most manga sites that well, especially sites with a lot of ads.

The doujin site, nhentai, runs amazingly well on it so I could really use a manga site thats like it is. I've spent a lot of time searching and can't find any luck.
