Rakudai Kishi no Cavalry (A Chivalry of the Failed Knight/A Tale of Worst One) is an school, action light novel series written by Riku Misora and illustrated by Won. The series first began in 2013 under SB Creative’s GA Bunko imprint. A total of 7 novels have been released, with 6 main novels and one spin-off. A manga adaptation of the series by Megumu Soramichi began last year being published in Monthly Shonen Gangan.
Here is a synopsis of the series from Haruhichan:
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.”
