Ichidensai Funaki

Ichidensai Funaki
Ichidensai Funaki is the father of the infamous Funaki twins Hyoma and Kazuma Funaki and master of the Funaki Dojo in Nissaka, in Kakegawa. In a tournament before the Lord of Kakegawa, Naotsugu Ando, he had a match with Kogan Iwamoto. The master of the Kogan Style ripped off Ichidensai's lower jaw, an action that was sharply reprimanded for being discourteous. For this reason, Kogan bears a grudge towards Ichidensai, which motivates him to send out Fujiki and Irako to kill his twin sons in episode 3 ("Kamaitachi"). His third child, who only appears in the manga (Vol. 11, Chapter 55 "Helmet"), is Chika, a girl who possesses similar strengh as her brothers. Besides his legitimate children, Ichidensai took in and raised the misshapen Kutsuki Gannosuke, who also only appears in the manga.

A trait common to the Funaki family is their monstrous strentgh, which plays a crucial role in the techniques of the Funaki School, including their main technique, Kabuto Nage. This technique involves splitting a helmet in twain in mid-air. After the death of the Funaki twins, performing this technique successfully becomes a prerequisite for marrying Chika, the remanining heiress of the Funaki Style Dojo.
