Coming this September
Aside from two different anime series, a great Vita port, and whatever else, Persona 4 also got a manga that was previously only available in Japan (in Japanese, except through fan translation).
Maker of fine books Udon is publishing the Persona 4 manga in English starting this September, “with future volumes releasing bi-monthly through the end of 2015 and into 2016.” You can find it in your neighborhood comic shop or on the neighborhood comic shop killing Amazon.
