Amaya

Amaya is one of the old goddesses of Yamato, revered by many. She normally takes the form of a small, quiet girl when she walks into human society. 
In the lands of the Oyakawa she is known as "Night Rain" the spirit that protects and blesses the inhabits of the Nakajima isles.
It is known that she does not tolerate "Giants" that tries to break out of their exile in the underworld.
