Futaba Yoshioka used to be an attractive and popular middle-schooler—well liked by the opposite sex, but ostracized by the girls. Nevertheless, she was able to brush all that off, because the only opinion that truly mattered to her was that of Kou Tanaka, a classmate with whom she shared a shelter from rain once, followed by quite a few other precious and significant memories. She even succeeded at making plans to meet with the quiet and innocent boy at the summer festival, but a simple misunderstanding, and Tanaka's subsequent disappearance, left her walking the halls of her school friendless. Now in high school, Futaba is not your typical adolescent girl. Determined to become a class favorite this time, she avoids all unwanted attention and, instead of acting cute and feminine, only stands out through her tomboyish behavior and disheveled look. But still, her world is soon turned upside down when the only boy she ever liked unexpectedly comes into her life once again—except he goes by the name of Kou Mabuchi now, and it is not his name alone that has gone through a sea change.

The hero king Inglis—who dedicated his entire life to building his country—is now approaching death. To award him for his honorable achievements, the goddess Alistia appears and grants him one wish. Having never been able to master the blade, Inglis asks to be reincarnated in order to do so. In a blink of an eye, Inglis finds himself born in the far future as a daughter of the Eucus noble family. Six years later, Inglis is discovered to be Runeless—incapable of utilizing the runes that enable the use of magic in this era. She is therefore ineligible to become a knight. However, this fits in well with Inglis' plan: she instead decides to become the squire for her cousin, Rafinha Bilford, allowing Inglis to focus on pushing her limits. For Inglis, the challenges this familiar yet different world has to offer are instead opportunities for her to hone her skills—and possibly become an extraordinary squire in the process.
