SPEC (Sega Players Enjoy Club) was a short-lived magazine by SEGA that started out life as a newsletter. It ran from 1988-1993. Several Phantasy Star related comics were included, some of which I have translated. If anyone has any special translation requests related to SPEC besides what is already here, just shoot me an email. Thanks!

In case the cliff hanger in Chapter 3 wasn’t frustrating enough, then I bet you will not want to wait to see what Yoshibon has to say about it in SPEC 8 😀
