Both Gegenji boys left home due to a conflict of interest with the head of the family - not entirely surprising when your father is old-fashioned and stubborn and his kids inherited said stubbornness. Gogonji believed that the family trade was outdated and archaic, and left to prove his new business plan by dealing in the buying and selling of information. Chachan was shaken by the argument between his elder brother and his father, and it struck a rift that ultimately resulted in his leaving as well. However, his reasoning was that he was a childish dork who wanted to play hero - and felt the weapons and armor they made should be used to help people, rather than just heap it on whoever is willing to pony up the gil and wish them the best of luck.
Chachan ultimately learned that his craft really can allow him to protect people - far more than he could through inept heroism. Gogonji continues apace, still resolute in his point even after his right as family heir has been revoked.
