The Pseudo-Kunoichi from Another World

The Pseudo-Kunoichi from Another World Summary:

The 21-year-old Kagura s.h.i.+no plays the role of a ninja in the ninja village’s Ninja Show. In her spare time she engrosses herself in Sengoku Online, a game based on the Warring States period of j.a.pan, and is quite the historical play otaku.
One day, the two worlds collide and s.h.i.+no finds herself transported into the world of Falyias where she is forced into the role of a pressure valve for the mana exchange between the two worlds.
As a form of apology, the world’s caretaker allows her to inherit all the powers of the character she played in Sengoku Online. With power that even the Demon King couldn’t scoff at, s.h.i.+no begins to live her life in another world.
