Doku: The Villainess Is Venomous

Mai Yoshimoto; she's lived her entire life in the shadow of her famous father and Sensei. She was taught to be just like him- The greatest Karateka that Japan has ever seen -but even though she mastered all of her father's techniques and had a fire burning in her that could bring cities to ash; she only remained as the daughter, and not a master of battle.

Juuri Hara Dai Nakayama; the only known daughter of the Nakayama Duchy. She's a hateful and malicious soul, but the role she was forced to play in life only made her that way.
Regardless of her past, people could only see her present. The evil version of Juuri.

What happens when Mai dies and is thrust into the body of Juuri? How will Mai- or shall I say Juuri -cope in a world full of magical creatures and powers?
