Manga with Sci-Fi genre:

Phantasy Star: Third

"The year is AW 1423, almost 200 years following the destruction of Mother Brain by a group of terrorists led by Motavian Agent Rolf. A young boy with no recollection of most of his life beyond his name and his mission runs into a group of hunters named Neithird and Duolos…" The manga Phantasy Star Third was done by Phantasy Star IV character designer, Yoshibon, for the Sega Players Enjoy Club in 1990. This work was published after Phantasy Star II and was used as the basis for creating Phantasy Star IV, a video game released in 1993. The manga is incomplete since the Sega Players Enjoy Club magazine folded; the final chapter ends abruptly after a swarm of robot soldiers attempt to surprise the trio at Third's house.
