Mikoshi Chiyo (Japanese: 御輿千代 Mikoshi Chiyo), also known as Torachiyo (Japanese: 虎千代), was an oni and a member of the Mikoshi Clan who lived around five hundred years ago. She was the biological mother of Iwakura Doukei and the adoptive mother of Mikoshi Nagamasa.
Chiyo was once a valuable ally of the Raiden Shogun Baal's and campaigned with her against the dark forces that emerged during the cataclysm. However, she was swallowed whole by a "beast of sin" and while inside its stomach, was tainted by the darkness. Even though she managed to rip the beast apart and slay it, she was forever changed: she would later turn her blade on Baal, after which she was defeated and badly injured. Her ultimate fate is unknown.
