Only people that watch the anime would actually understand this manga.....but man....how I wish the anime had this type of "Serious" feeling...."Intense" is more correct.

Before the anime, the franchise started with stage play #1 The LIVE. This manga is adaption of that stage play (which also has been English subbed).
The stage play's sequel is #2 Transition, which also has on-going manga adaption by the same artist.
The anime ended, but has some continuation in form of manga Overture chapter 10, various short OVAs that's shipped in the blu-ray, and the mobile game Re LIVE (English version recently released) pick up the story with new characters, and that'll get a short comedy anime soon.
@SuperOniichan Yes, although it's more like loose continuation. There are timeline oddities but both the game and stage play #2 can be treated as if they're continuation of the anime events.
