Musha Gundam
SD Sengokuden first started in Comic World, drawn by MARSHI a.k.a. Imaishi Susumu. Comic World is the comic part of the instruction manual of BB Senshi No.17 Musha Gundam. Comic World tells the story of seven Gundams. With that concept, BB Senshi maker, Bandai together with Comic Bom Bom supplemented and expanded the story of Comic World. This led to the full-length manga series, SD Musha Gundam Fuunroku(SD武者ガンダム風雲録) with original character design by Yokoi Kouji and art by Yamato Kochi. SD Musha Gundam Fuunroku is the manga compilation of the first four works. Comic World still exists in the instruction manuals of recent Musha Gundam BB Senshi releases, but the artist wasn't always MARSHI.
