A japanese girl who comes from a rich family. She is very calm and nice most of the time, but if you try to come between her and her man, she'll turn fierce. But if you're on her good side, you'll have the pleasure of knowing the beautiful woman. And although she tries to be tough, she's actually pretty fragile.
When she was talked into believing Scarlet kissed Kurai, Etsuki was torn. Her tough exterior was torn to reveal her soft inside where she was weak and emotional.
