Sanjo Riku

Riku Sanjo is a mangaka who has also had experience writing anime and TV show scripts.

While his most notable project is Dragon Quest: The Adventure of Dai, as well as Beet the Vandal Buster with the same artist, he has also worked on other projects - notably, he was the head screenwriter for toku series such as Kamen Rider W, Zyuden Sentai Kyoryuger, and Kamen Rider Drive, as well as anime such as Gaiking: Legend of Daiku-Maryu and the 2007 adaptation of Gegege no Kitaro.

He is also known under the pen name of Rokuro Sano, under which he wrote Ziga for Weekly Shonen Jump in 2018. Whether the pen name was to differentiate Ziga from his other works, to prevent the series from coasting on his name alone, or another reason is unknown.
