Yes, there's the ones already mentioned, which are done by Colman Ó Raghallaigh: An Táin; An Sclábhaí, Tóraíocht Dhiarmada agus Ghráinne; and one or two others. They're fantastic!
There's also a comic book called Rí-Rá, although I'd say it's aimed more at kids.
There's no manga, though, to the best of my knowledge.
Tá mé mar atá mé, agus ní fhuil mé gan locht. An té atá saor, caitheadh sé cloch.
(Only kidding... please feel free to correct me anytime!)
