Tytania, Jouslain

ジュスラン・タイタニア

A calm and wise duke, widely viewed as the probable successor to Ajman as clan lord of Tytania. Among all the dukes, Jouslain clearly favors peaceful methods the most. He maintains a unique, long-standing friendship with another duke, Aryabhata, and is frequently the target of Idris's frustration. Jouslain's character receives more exploration than that of the other dukes in the series, primarily through interactions with several individuals who appear dear to him, most notably Aryabhata, Bal'ami, Francia, and Princess Lydia of Elbing.
