Plot
In the Kingdom of Silvare lived the Hero-King Inglis. With the personal blessing of the goddess Alistia, Inglis became a divine knight, slaying the enemies of humanity and the dark gods to establish the Kingdom. As a last favor granted to him on his deathbed, the goddess Alistia reincarnated Inglis as his single greatest regret was not being able to reach the peak of mastering the blade. Now reborn as a woman (perhaps at the jesting whims of the goddess), Inglis Eucus strives to live a life in the far future where she can truly master the blade.

Characters

 * Inglis "Chris" Eucus (イングリス・ユークス)
 * The main protagonist of the series and the Hero-King of the Kingdom of Silvare, who reincarnated as a woman in order to dedicate her new life to training martial arts. She is also known by her nickname Chris. Despite accepting her new life as a woman and having girlish habits like a love of desserts and fancy clothes, she still retains parts of her previous life, like liking only women and seeing her friends as grandchildren. She possesses ancient magic called Aether, which most people in the new world do not understand, making her extremely powerful, even though she's a Runeless (although some characters like Ripple, Yua, and Black Mask are strong enough to fight back against her). She loves to battle and is very overconfident, showing little to no timidity regardless of how strong her opponents are and usually begs them to fight her if they aren't interested, to the confusion of friends and foes alike. She also has a powerful appetite.
