Does iriya die in Iriya no Sora?

I just finish watching Iriya no Sora, UFO no Natsu and as bad as i thought it was the last episode made me cry. i guess i just dislike the 5 episode but whatever. Iriya no Sora, UFO no Natsu turned out to be a great anime. evoking so much emotion in just 6 episodes. anyway the end is left unresolved. so does Iriya die at the end or does she live. asaba said hed turn the world upside down and let humanity die just to be with Iriya, and Iriya said she wanted to be with Asaba. so did she live or die.
