We don't know... So far we only have the 1, from ep 1-25, (though some people say it's 2 seasons, i just go by arcs)

There are 4 MAIN story arcs in the books. If we were to make everything that was published, into an anime, it would probably near a hundred episodes... (if they don't cut out content, like they did with this first season)

HOWEVER... The chance that it will actually be done, is uncertain. It's all a matter of money, and whether or not the anime studio feels they can profit off another season...
