Chivalry of a Failed Anime more like.

Blazers are knights with special powerful abilities, due to his notoriously low magical ability ranked a lowly F-Rank, Ikki Kurogane is subjected to conditions that directly hinder his progress through school from his family, dubbed the "Worst One" however he's given the condition of being allowed to graduate should he succeed in the Seven Star festival, using some clever techniques to compensate his lack of magical ability along with a trusted friend group with new girlfriend Stella Vermillion, sister Shizuku and the sassy Alice, Ikki aims to prove his family wrong.
Yet another school for heroes with an Op main character and a fiery red headed love interest, were made to believe this is going to turn into a harem series or go heavy on the fan service but it quickly becomes apparent that the focus is fully on Ikki, and every other character is a side character or just another opponent, what's strange is that Stella Vermillion is given top billing on all the covers including the physical copy on Blu-ray, yet she does practically nothing of importance; apart from some impressive fight scenes, the story is incredibly mean spirited to the point of absurdity, it's the Food Wars problem of threatening expulsion every episode, the stakes lose their impact.
Dub is fine if predictable casting.
Final Verdict: Absurd plot only barely saved by decent fight scenes with a side cast that barely does anything, leading to a very unfulfilled anime you were likely tricked into buying because you saw a pretty red headed girl on the front.
