"Her name is Mirai Yoshida. She was not born in Japan. She is not supposed to be in 1864. But, through a time-travel mishap, Mirai is stuck with no way out. Help may be found when she befriends Hatsu, a humble tea mistress harboring a dangerous secret. Yet time is running short for the entire nation, because Mirai knows that the shogunate is about to fall. Learning the way of the sword might be her only path towards survival."--Publisher's description.
