Sigiswald

Sigiswald (ジギスヴァルト Jigisuvaruto) is the first prince of the kingdom and Anastasius's older brother.

Sigiswald is married to a woman from a middle duchy. Once he marries a woman from a great duchy, she will become his second wife.

He asked for Eglantine's hand in marriage, but unlike his younger brother he did so solely for political reasons, since the one to marry her is almost asured to become the next king.
