Iosif Aysberg

Iosif Aysberg is the older brother of Ilya Aysberg and the self-proclaimed true Tsar of Iceberg.

Being a male member of the Aysberg Family, Iosif was born with barley any Magic power, and despite being the first-born of royalty, never had any hope of taking the throne of Iceberg. Furthermore, since he was male, he was viewed as 'useless', and while he wasn't mistreated, he never received much in the way of affection. Unsurprisingly, his made him extremely jealous and bitter towards his younger sister, Ilya, he viewing her as a thief who stole the life that should've been his.

Upon becoming a legal adult, he left Iceberg and journeyed Ishgar in search of a method of increasing his Magic power. His travels eventually led him to the Pergrande Empire, and while exactly what happened is unknown, it is believed that he traded top-secret information about Iceberg to the empire in return for a Dragon Lacrima and a position among the Ten Headed Hydra.

Despite disliking Pergrande for its many invasions of his homeland, Iosif is willing to work with them if it means overthrowing his sister and taking the throne of Iceberg for himself.
