He likes to "beat up" his best friend, AYATO to the point of tears. As a child, he was thought to be considerate and bright. Before his accident, he was caring and highly talented. He was thought highly of by his peers. Kurono is a vampire, just like his sister, however he only possesses one Aster Eye.

Name Meaning

クロノ Kurono - "Mysterious" or "Dark"

鬼星 ASTER - "Star" Demon


ASTER Kurono is the elder brother of ASTER Kurami. He was presumed to have died during a snowstorm accident where both siblings' lives were jeopardized. He made a dire attempt to save Kurami, but he lost consciousness during the event. In the hour after they were rescued, only Kurami could be revived, therefore pronouncing Kurono as deceased. Although she knew that Kurono was not actually dead, she did not speak up due to fear and shock, and he was buried as a result.

Upon being buried alive many miles from home, Kurono was clinging to his last strings of life when a Star Demon came to him in a dream and offered to save him in exchange for his soul. Now, having taken the offer, Kurono is a new person... He is neither dead nor alive, and ethereal, with a murderous heart of revenge for Kurami.
