The Hergula: While many modern-day manga/anime fans might not know about this individual, let me tell you right now, it is important that you do, as he is considered one of the most noteworthy people in the world of manga.

It was a sensational manga at the time, one that enabled Hirai to write more and more. Not only that, Kazumasa Hirai also has his name attached to Genma Wars (Genma Taisen) as the writer of the manga. He wrote a number of novels as well, such as Tiger of Megalopolis, Zombie Hunter, Abduction series, 21st Century 8 Man and the Wolf Guy series.
