Rúrik Sveinnsson Svarthæð (ルーリック・スヴェインソン・スヴァルトヘイズ, Rūrikku Suveinson Suvarutoheizu) Rúrik is the first prince of Svarthæð and seems to have been kept on a short leash due to his hobbies which seem to be even more offensive than Sigurð's attitude and partying. His relationship with Criet is unknown but during a party, he is shown to be sexually molesting his sister Helga before Naoya 'accidentally' fires a champagne cork in his direction interrupting his fun. In the manga his personality comes across as a pervert with a sadistic streak.
