He is now a loyal servant to Sei and head of the Marine Bank in the Special Zone. While Cain uses every chance to disrespect Jiro, he thinks highly of Jiro's powers and skills despite believing Jiro to be immature.

Dark Princess of the North Sei's older sister whom Sei greatly respects. Kotaro commented that both she and Sei do not like to talk much-(mostly his sister).
