Roshigumi

Roshigumi was a Ronin force which formed by the Tokugawa Bakufu to guard Shogun Tokugawa Iemochi in 1863. It was planned by Kiyokawa Hachiro. But Kiyokawa suddenly changed the purpose of the Roshigumi just after they arrived in Kyoto. He tried to use them for Sonno Joi, then the Bakufu called them back to Edo and Kiyokawa was assassinated shortly after.
