Satsuki

Satsuki is the second girl to whom Takashi allowed to live with him. She is a catgirl. Takashi found her on his way back from school and offered her a shelter from the rain because she has been standing still stunned from the it. After this he allowed her to stay with him since she didn't have a place to go as well.
At first she was stubbornly closed minded, later she opens her heart slowly after she saw how Choko and Takashi get along good. She is now helping out around the house. Satsuki is modest, quiet and extremely shy, to the point she would look down and turn red when praised.
