2042, New York City: A day in the life of college student Mirai
Yoshida means studying Japanese history, learning swordmanship,
flirting with her TA, and preparing to travel to Japan in 1864.
Everything changes once she goes back to the past.
Mirai and her classmates are ambushed by rebel samurai. Her
friends are killed, her time travel machine is lost, and Mirai
ends up marooned. In order to survive, she disguises herself as a
wandering samurai and is hired by Hatsu, a tea waitress, as
bodyguard for her travels.
