ルナアイズ・ ヴァーミリオン
from Rakudai Kishi no Cavalry
Lunaeyes was born to Sirius Vermillion, the Emperor of Vermillion and Astrea Vermillion, the Queen of Vermillion. She also played with the 1st Prince of Cradleland, Johann, when they were young and went to the same college. They were so close that they were described to be like siblings. During Johann's time studying abroad in the United Kingdom, he got mixed up with a bad crowd, due to the pressure he was feeling of inheriting Cradleland's throne. However, Lunaeyes was able to make Johann quit his dangerous activities, bringing him home and scolding him. This saved Johann's attitude greatly, causing him to become more responsible and dignified, as well as making him all the more grateful to Lunaeyes.

The "school sword action" story revolves around Magic Knights, modern magic-users who fight with weapons converted from their souls. Ikki Kurogane goes to a school for these Magic Knights, but he is the "Failed Knight" or "Worst One" who is failing because he has no magical skills. However, one day, he is challenged to a duel by Stella, a foreign princess and the "Number One" student. In this duel, "the loser must be obedient for life."
