I just checked it for future, but there is jump from ch. 38 of volume 11, to volume 19.
I see I am shame of myself I thought the 28 volumes were complete, but not. Right now I am looking where you can read it. Sorry the reason I didn't know is that I grew watching Saint Seiya the anime I have never read the manga until now I am reading Next Dimension because there is not continuation in the anime.
The only solution is watching some episode from the anime until you get where is complete. The other is that Viz has complete the 28, but I believe you don't want to buy a manga you barely know.
