SPOILER:


At the end of episode 13 Yuzuru says something about when Yuri, Kanade and the others disappear same for Yuzuru they'll have a NEW life, that's why in the ending of episode 13, its been confirmed that the boy with the same hair as Yuzuru WAS Yuzuru after all since he has a new life, as he walks forward there is a girl with white hair that resembles Kanade. Yuzuru stops walking, Kanade walks the other direction where Yuzuru is heading, so Yuzuru turns and runs toward her and reaches for her shoulder or hair to get her attention. I believe that his life in the after life will be the same in the real world. He'll meet Kanade again and then yuri and the others
