One chapter? well you can't really write a good review on one chapter but i just wanted clear some things up...
From what i can gather Kazusa Takashima (the author) got caught up in a legal battle and lost back in 2004. Due to this she decided to take a break from her work. According to Wikipedia she resumed work in 2007 and completed a few of her mangas, but not all.
So being that Dragon x Boy was released in 2003 and since then no other chapters have been released; i can pretty much assume that this is one of her mangas she is not going to continue :(
With that being said the first chapter is promissing with nice art and plot introduction...but alas, an unfinished manga with no hope of finishing on the horizon is kinda a waste of time :/
In the end it's only 14 pages so i'll let you decide :) read more
