Yamada, Denzou

山田伝蔵

Well-known and respected for his career, first as a highly skilled active ninja and later as a teacher, he serves as something of a fatherly figure to Rantarou and his classmates. He is especially proficient with flintlock rifles. Whenever he needs to move about in disguise, he usually jumps at the chance to crossdress, much to the exasperation of anyone he is with, as he is very unconvincing. However, he himself has absolute confidence in his crossdressing persona, whom he calls Denko.
He is married to a mysterious and famously beautiful kunoichi, but since the Ninjutsu Academy is far from his home, he does not see his wife very often due to his job. Their adult son Rikichi, a ninja himself, often ends up acting as a messenger between them.
