Yeah, Tokyopop stopped publishing them. They released Reload through volume 9 and then stopped. Last I heard, you could only find english!Vol 10 released by the publisher Chuang Yi. But it's so rare it's basically online only for most of us; I don't even have it.

And Blast is of course only in Japan for now, but saiyuki_manga puts scans and translations up (and has Reload 10 up, too). It's open to join.

Saiyuki Ibun is also on that community, for all your Koumyou-Sanzo-was-such-a-punk, goddamnit-I-would-RP-him-if-it-wouldn't-break-our-Sanzo needs.
