Do you even know how animes are created? Anyway, no, the author of Mondaiji-tachi ga isekai kara kuru sou desu yo? did not die or had some serious reasons for him not to continue the anime. Why? Obviously because he only writes the Light Novel (which has 12 Volumes and a sequel restarting at Volume 1 with other Characters including old ones). The animation studios have to pick this Novel up, which will be in at earliest Fall 2016 in my experience. Mondaiji will probably get another Season in another 2-3 years.
