Well I stumbled upon this whilst looking for news on KH2 and it looks sublime, especially the art. Yoy can download the first 13 chapters and I guess more to come. Aparently it is being published to be relesed.

i read the first chapters- the art is wonderful but i didn't really like it. it sticks to the games story but still misses a lot out, i think mangas based on games work better when they are adapted to make it more interesting.

Shiro Amano is an incredible mangaka. I haven't read Kingdom Hearts yet, but the German release is getting near, so I'll soon have a look at it.

It certainly looks prettier than his Legend of Mana manga, but on the other hand, I fear there'll be less of this weird and amazing kind of humour... :(
Yeah, Shiro Amano forever!!!
