Mishima Sae

She is an active sex worker and brothel owner. She has been taking care of women who have no relatives or no place to go back to.

She has overcome the harsh world by using her body as a weapon. She is a kind and strong woman at heart. However, she is also filled with bitterness and vengeance against Takeshi's late father.

At first, she uses Takeshi's "search for maman" as a means to get rid of the zaibatsu ruled by Takeshi's late father

As she gets to know Takeshi, the more she thinks, "I am his mother without a doubt".
