That song fucking spoiled me the manga, i'm sooooooo mad. If you see a live action performance of this song on Youtube, DON'T WATCH IT!
I went to youtube to search for it and among the results was a live action video. I thought that it was played at a concert or something so i watched it for a while but then noticed the description that said
that it was from the movie adaptation of the manga. So now i know that
Kenji is alive and he'll be playing that song at the end of the story
Oh for fuck's sake.
The song is nice though.
