Very little is known about Ryu Mizunagi but the author's birthday is March 23rd. Originally from Aichi, Mizunagi won the Kodansha Four Seasons Manga Award in 2004 with the pilot for Witchcraft Works. Mizunagi was able to continue the project through Kodansha Japan in 2006.
"Witchcraft Works has proven to be a pretty funny reverse take on the whole damsel in distress trope...With so much going on, it's easy to find yourself enthralled by the action this time around." --Bento Byte
