Hida Ninja Clan
A group of elite ninja that lived hidden among the mountains of Hida.
Utilizing thunder, water, earth, wind, fire, metal and flower - through these seven different styles of superhuman techniques they were known not only for their intelligence gathering network, but also for their combat prowess.
They served under Toyotomi Hideyoshi until they disappeared after the Battle of Sekigahara (although unofficially there are records of their participation in the fall of the Tokugawa shogunate). After the Meiji Restoration, they were in service to the Japanese Government and continue to do so to this day.
This is the history of the Ogawa Family.
The previous head of the family, Kunimitsu Ogawa, also fought for the greater good outside of the public eye similar to the Adaptors. He fought against the Taurus Twins who sought greater Westernization, and was a key part of preventing their "Sanctuary Plan" from reaching realization. There are many stories of his battles against evil in the shadows that helped to create the peace of today.
