Knee-deep in debt, Black Knight Judith's whole life revolved around money. She only bothered with actions that would net her a profit; no matter how unscrupulous the deed, it was fine as long as she was paid. However, after her superior stabs her in the back, she begins to rethink the tenets she has lived her life by.

The next thing she knows, Judith has returned to the past, before she joined the Order of Black Knights. This time, she resolves to become a true knight—one who will not waver in the face of money and wields her sword with honor. The perfect opportunity to do so arrives when Captain Kaillou Lewalmeigh offers her a place in the Order of Red Knights. Abandoning her former cloak, Judith dons the red uniform, resolving to leave behind her money-grubbing habits and embrace the morals and righteousness of knighthood.
