Tactics

一ノ宮勘太郎

Kantarou's features are stark opposite of Haruka's. His short, slightly wavy, hair is a light, silver-grey (almost white), while his large eyes are red. He has a pale complexion due to him being an albino. Despite being an adult, his soft features make him seem more like a young boy than a man.

春華

Haruka (春華, Haruka) is a oni-eating tengu, the strongest of all youkai. Kantarou Ichinomiya, having named him, became his master and friend. Haruka has the ability to control lightning. Occasionally, such as when he is attacking oni, Haruka can transfigure into his true youkai form. His nails grow sharper and longer, his fangs grow longer and his eyes constrict. Usually, he appears as a tall, dark-haired man with black wings that he can either hide or reveal. Haruka is troubled by his lack of memories, inability to eat youkai, and loss of power, which starts to affect his sense of self. Haruka's name under his previous master, an onmyodo practitioner, was Rin. As Rin, he did not have a good relationship with his master, and it is hinted that she took advantage of his subservient status by making him eat youkai she didn't like.

ヨーコ

Youko (ヨーコ Yōko) is a female kitsune youkai whom Kantarou Ichinomiya named. At the beginning of Tactics, Youko had already been living with Kantarou. She is loud and impulsive who often loses her temper towards Kantaoru. Youko has the ability to make her fox ears appear and disappear at will, and can turn into her fox form if she wishes. Youko is shown to be deeply concerned about the household expenses and pesters Kantarou about finishing his book manuscripts. Before joining Kantarou, Youko was initially a lonely youkai who deceived travelers into thinking she was a member of their family. Youko pretends to be Kantarou's wife, but Kantarou soon reveals her to be a youkai and invites her to join his household.

ロザリー

スギノ様

Sugino is a white tengu and the "god" of Sugino Village. As such, he is often called Sugino-sama. Unlike a black tengu, who is born a tengu, a white tengu was originally a powerful, overly-proud human priest or monk who changed into a tengu. Before Kantarou had tried, Sugino had attempted to break Haruka's seal, but failed. Sugino has a great amount of dislike for the human race, having been a human himself. Sugino is married to Muu-chan, a small, green youkai. Upon being asked how they would reproduce, Sugino states that their relationship is platonic. Prior to meeting Muu-chan, Sugino was a cruel character who earned the nickname of 'violent tengu'. His cruelty caused him to be lonely and hate his immortality.
