I read the entire Guyver manga in English on a site called mangakakalot (https://mangakakalot.com/chapter/guyver/chapter_3). The watermarks on the scanlations all said "Guyver advocacy," but I didnt know what that was referring to until I went searching for the last volumes, #30-32, of the Bio booster armor Guyver manga. In my search, I came across an article on the Guyver wiki (https://guyver.fandom.com/wiki/Guyver_Advocacy) saying that Guyver Advocacy is the group that works to promote the popularity of the Guyver in the West and that they are the official English authority for translations. So it is to your group I owe a great debt of gratitude! For helping me rediscover the first manga my father introduced to me at the age of 6 and rekindling the fire of my own willpower and other self!
