Owaranai Kisetsu no Mannaka de

"Don't you want to experience a love like that some day?" As dreary days roll by, who should appear before Tokiha Sai but Emiya Hanabi, his childhood friend and first love, who he had alienated long ago. That is the start of a day that seems like a dream. Hanging out with former friends like the old days, this time is irreplaceable. "This world is our ideal world - a parallel world." There's only one way back to our original world. We have to find the magician that brought us to this world while we're still on summer break. And then we have to decide between this ideal world and the real one. If you could go back to those days, what would you do?
