Does rin okumura die

No. They only animated about up to the 30 manga and stopped. Rin does not die in the manga or anime. A movie came out, but it has not been english dubbed or subbed. Rumors about a second season after the movie are going around. Since I have not seen the movie, I can't say if he dies or not then, but Rin Okumura does not die in the anime or manga.
