In the novel Lyle participated because he was an Imperial Knight and personal knight of the second princess, Madeleine. Of course, he won the tournament and was awarded a *Star of the Grand Cross of the Iron Cross, if I remember in the novel, it was stated that it is a kind of medal.
(*The Star of the Grand Cross of the Iron Cross was the highest award to the most outstanding knights who performed feats of leadership to the extreme benefit of the Empire. *)
Since Lyle won against a hundred knights he was known as the strongest knight.
However, will he still win against my knights? I already prepared them if they came across Lyle, he once taught me about swordsmanship, and I already know quite a little of his fighting style and I used it.
