Jūgo Kannagi

Jūgo Kannagi is the current head of the Kannagi family and Ayano Kannagi's father, as well as the first cousin of Genma Kannagi.

Personality
As the head of the Kannagi family, Jūgo is responsible for directing the other members of the head family and branch families as well as the Fūga Clan. Therefore, compared to most members of the family, Jūgo is very calm and lenient. He is often portrayed as calmly sipping tea. He treats all of the younger members of the family nicely, opposite to how their actual parents treat them.

Despite being the head of the family, Jūgo is easily one of the most humble members and in fact always disliked the family's tendency to look down on people who don't use Enjutsu. Contrary to the typical Kannagi doctrine that places merit solely on strength in using fire, Jūgo 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.

Jūgo is also a very practical man, willingly agreeing to Kazuma's demands for money in spite of how selfish they are as well as attempting to get him and Ayano together, as he believes Kazuma's great power is essential to the survival of the family.

History
Over four years prior to the events of the show, Jūgo was involved in a traffic accident that claimed the life of his wife and took his leg. Because of the injury, Jūgo was forced to retire and the Right of Inheritance Ceremony was rushed.

Enjutsu (The Purple Flame)
Prior to the show, it could be assumed Jūgo was a master at Enjutsu because of his current status as the head of the Kannagi family. He wields the Purple Flame of Purification and was considered to be the strongest member of the family, though he gave up the title to Genma Kannagi after losing his leg. It is implied that he wielded Enraiha before passing it to Ayano.

Ayano Kannagi

 * As her father, Jūgo is tough on her as the other parents of the family are but he is significantly more lenient with her. He sees potential in her but wants her to slowly develop her abilities and maturity. He often plays matchmaker for his daughter by setting up Kazuma and her on missions.

Kazuma Yagami

 * Jūgo is one of the few Kannagis who felt genuinely sorry for Kazuma during his adolescence. In the light novel, he admits that he feels that Kazuma's pain was partially his fault since the Right of Inheritance Ceremony was hurried up because of his accident. Upon Kazuma's return to Japan, Jūgo saw Kazuma taking up wind magic as a path to happiness despite the rest of the clan mocking him. Jūgo plays matchmaker for Kazuma to help strengthen his ties with the clan and to preserve the future of the clan.

Ren Kannagi

 * Jūgo, being the head of the Kannagi family and once the first cousin of Ren Kannagi, is seen to care much about Ren's wellbeing like his own daughter, Ayano, and treats him like a son of his; Ren, in return, holds much respect for Jūgo in his family head's position and finds it easy to talk to him and sometimes share his thoughts or feelings. In this sense, Ren may appear closer to Jūgo than his own father, Genma, giving the impression of another fatherly figure towards Ren with their relationship being likened to a father and son. Jūgo is often seen throughout the series conversing with Ren while he is giving him a full-body hand massage in the Kannagi family home. Much like Jūgo, Ren is a big supporter of the growing feelings between Ayano and Kazuma and hopes the two will one day be honest with their feelings; Jūgo himself had recruited Ren into his many planned outings for both Ayano and Kazuma.

Genma Kannagi

 * Both Genma and Jūgo highly respect each other, being that both individuals are among the most powerful and strongest skilled Enjutsu users in the Kannagi family with Jūgo wielding the Purple Divine Flame of Purification and Genma wielding the Azure Divine Flame. Jūgo was considered to be the strongest member of the family, though he gave up the title to Genma Kannagi after losing his leg. Though they do hold high respect and treat each other civilly in general, they do share a casual friendship as two elderly family men and also due to the fact that they were once first cousins.

Kirika Tachibana

 * Kirika Tachibana and Jūgo share a business-partner relationship, being that Kirika's police department started working closely together with the Kannagi Family as their new partner for communications and information, in replacement of the Fūga Clan's betrayal. Though strictly being work partners, Kirika is seen to be involved and lending a hand in the Kannagi family's problems several times, such like the operation of securing the premises when the Ōgami family of the Kannagi Family Clan tried to apprehend Misao Ōgami when she turned evil at one point in Episode 6, locating Ren Kannagi's missing whereabouts when he ran off with Ayumi Tsuwabuki in Episode 10 alongside, and tracking Kazuma Kannagi's whereabouts when he went rogue during the Pandemonium Arc during Episode 23. Kirika is often seen submitting reports and information to Jūgo within their business-partner relationship during the many occasions she visited the Kannagi Family's home.
