Azure was given to Lightning Razgriz the day he turned 14, the two became inseperable after their initial meeting. He follows Light around and will do anything for him.
He is used mainly to transport letters, as Lightning rarely wants it to participate in battle.
The raven can use Fire and Wind releases, has speed equal to that of its master and about half of his chakra, additionally the raven has a razor sharp beak and talons. Lightning performs the required seals for the techniques Azure uses, (except the explosive clone technique) and it uses up its chakra rather than his own.
The raven is Light's partner and tends to follow him around, he is quite affectionate towards him and his family, even "rubbing up against them like a cat." He always follows Lightning into battle, and tends to keep opponents distracted, typically, Azure is using the Explosive Shadow Clone technique to keep himself safe, but most of the time Lightning doesn't notice.
