An emotionless puppet that can't feel anything. The puppet is calm with no killing purpose . She is a creation of an inhuman experiment. She has her own thinking. She has feelings but it seems like those feelings are lost since she has been through so much pain and suffering. 

A little girl puppet without any emotions

Okane is somber and cold, cloaked in an air of quiet isolation.
She walks alone, untouched by warmth or sympathy.
Merciless in words and presence, she is a force as unforgiving as the sea itself.
