Personality
Aster initially carried a pious and self-righteous demeanor as he aims to crush any opponent with a religious fervor when complete his jobs as an Assassin Due to being unfamiliar with Earth Day Life he is curious to the point of naivety believing TV shows are real.

Aster has shown complete apathy often questions Rito about why they must aid people who either have nothing to do with him or he dislikes, Rito replying that it is the right thing to do He also refuse involved himself in fight that he can't win as shown by him refusing to fight battles he knows he will lose. This was proven to be true as Rito lost to Dangerous Foe like Slade, showing just how much more calm and collected he is
