Mukou Azumi

Sora's childhood friend. They have a hate/attachment (neither of them would ever admit to caring about the other) relationship, and they are constantly teasing one another/at each other's throats. She is in love with Shinnosuke.

She despises all other Hunters on an instinctive level, though she loves her adoptive big sister, Misora. She is highly intelligent and also a natural survivor, avoiding danger with a frighteningly high degree of natural cunning and what looks like instinctive foresight. The only thing she hates more than Hunters is Devils. She always works alone so that she won't accidentally kill one of her fellows on impulse.
