If there is a second season, it'll be awhile since it seems to follow with the manga. New chapters of the manga only come out once a month. If I remember correctly, the anime stopped somewhere like ch. 34 and the manga is only on ch. 55 so far. (I haven't read the manga yet, so someone correct me if I'm wrong.)

I'm also pretty sure a dub is in the works since it's incredibly popular. Funimation will want some of the profit that the series will bring it
