Ryujin Mizukawa

A wandering Samurai who, the night before he was due to head back to Hingashi, got Kazuko a warm meal and a place to stay for the time being, and later found her after being attacked by an Alpha Vodoriga. Kazuko seems to have a fondness for the man, not having known too too many people from Hingashi. He is also planning to take Kaz to Hingashi someday, and upon telling Kazuko that he fought demons and voidsent, she offered to join him-and wished to use her connection with Gouken to possibly get more assistance with dealing with Hingashi's demon problem. In the meantime, she's being trained to help take them on.
