Hida Jakuchu

Hida Jakuchu of House Kakeguchi was the brother of Hida Kakeguchi, the founder of the Kakeguchi vassal family. Kakeguchi was a friend of Hiruma, and when Hiruma, Kaiu and Kuni were rewarded with founding each of their families Jakuchu was angry. Jakuchu believed they had abandoned the Crab while Kakeguchi and he had remained behind and defended the clan loyally. Secrets of the Crab, p. 23
Jakuchu told Kakeguchi that he was angry with Hida because Hiruma and the others were rewarded and Kakeguchi stayed to his post and was rewarded with nothing. Kakeguchi chastised his brother, saying, "We all must play our parts, Jakuchu. I do not do what I do with thought of reward. Hiruma's title is not a plaything; the family Hida has granted him will be as much a burden as a reward. That is his destiny. It is our destiny to guard Hida, and if you do not understand that you are not my brother." Secrets of the Crab, p. 24
Jakuchu was ashamed and promised to stand by his brother loyally for the rest of his days. Hida overheard this and joined them. He promised that Kakeguchi's name was always to be remembered for the wisdom of both brothers, and their descendants would take his name alongside the Hida name. Jakuchu eagerly asked to be the first to swear fealty to his brother's name.
