Contrary to the typical Kannagi doctrine that places merit solely on strength in using fire, Juugo has been trying to stop discrimination against not only the Fūga Clan but the users of other jutsus as well. He also regrets not being able to stop Kazuma's expulsion from the family. Believing that Kazuma Yagami is essential to the Kannagi's future, he constantly creates situations which force Ayano and Kazuma to work together in the hopes that they form a relationship. He is voiced by Masaki Terasoma in the Japanese version of the anime and R. Bruce Elliot in the English version.
