Rakudai Kishi no Cavalry

Chivalry of a Failed Knight

A shounen that doesn't oversell its action yet nails the romantic tension between leads. The setup hints at melodrama, but what really hooks you is watching two supposed enemies become each other's strongest support.

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." (Source: Anime News Network)
