When Black awakened his eye form, it was immediately at level 2. His family had a large library, which he managed together with Agatha. He is a very generous Primordial, with a capital letter.

Even before the death of God, Hiro was a warrior in one of the special combat units, but not an elite one, as his eye form hadn't manifested before the genocide. He grew up in a wealthy family, where he was taught manners and etiquette, as well as martial arts and much more. He was successful, respected, and famous throughout life. After the genocide of the Primordial race, he was one of the few survivors, wandering the world extensively, sometimes working in schools, unverstates, and more prestigious educational institutions, or teaching someone personally. After a great deal of time, returning to the world of the Second Heart and meeting the perpetrator of the genocide, he was able to sincerely forgive him, even teaching him a few tricks of the trade. He was one of the few who treated Purple without prejudice, with kindness and understanding.
