Keep your copies of September's Young King Ours if you have them - Rikdo reworked the ending chapter for the 27th tankobon.
Less chaotic, more sentimental, IMO. Adds the Leiji Matsumoto Parody characters for a brief cameo, gives Watanabe a much happier ending, and has a "I drew this for you, Uncreativity" final page. And no, the volume does not include either of the 'hot spring' epilogues.
But yes, it still has that Shiouji ending. WTF.
Holy poop on a post! Glad I bought the magazine.
No heavy spoilers please, but... how different are we talking here? Like, is nothing the same (not even the art), or were just a few scenes changed into something else? Oh yeah, and which ending is better/more satisfying/more fitting/whatever?
