Shirou dies in the caverns due to his Reality Marble's effects on him, and reincarnates into a new family. Noble they may be, but very poor! But still, he's fine with it as long as he lives well. But as a baby who can understand everything since day one, he picks up on things...but with a catch: he is reborn as a GIRL to a Laynoble Family and his future depends on him alone.

On her deathbed, Myne gains the memories of a Japanese woman, starting her off on a lifelong journey. Only this time, it isn't an inspiring librarian, but a powerful magus with dreams of becoming a true Magician. Equipped with Rin's memories, Myne is on a mission to gather all the knowledge she can and master the Mysteries of this new world.

Ferdinand's over reliance on potions became his downfall. Left too exhausted to remain conscious he was poisoned and on the brink of death, when Shirou's soul entered his body. Now the living sword walks the land of Yurgenschmidt, and is not inclined to play by noble rules. Myne is gaining a lot of attention, but her guardian has different objectives this time around.
