 * Elizabeth Ashley (エリザベス・アシュレイ)
 * A teen-aged noblewoman. She occasionally meets Sei in the palace library and they talk. She becomes a friend of Sei's and allows her to use her nickname of Liz.

She is a daughter of a Marquis, the fiancée of the crown prince and a junior at the Royal Academy; the high school for the noble's children.

 * Aira Misono (御園 愛良 / アイラ)
 * The 16-year-old girl that was summoned alongside Sei. She is the one the crown prince declared was the "Saint" and he has been keeping her in tight control since her arrival; largely due to his promise to do all he can to try and find a way home for her (after seeing Aira break down crying in despair that the summoning couldn't be reversed). She attended the Royal Academy as a senior while under the control of Prince Kyle. Unfortunately, Aira unintentionally causes trouble due to being unaware of the class system that wasn't present in her world; largely the prince's fault for not considering it. After graduating, she joined the Royal Mage Academy to further her studies of magic. She shows an affinity towards water magic.
