In the manga, do Satoru and Airi get together? I know Satoru and Airi didn't get together in the anime. Do they get together in the manga?
As this answer discusses, in the manga Airi shows up a few times while Satoru is recovering after his coma, although they never really directly interact. While the ending of the manga is quite different to that of the anime, the very last scene is the same:


   Satoru goes back to the spot under the bridge where he hid from the police, and as he hoped Airi shows up there as well.
