Sohma Momo

Sohma Momo is Momiji's younger sister. She is unaware about the curse, or the fact that Momiji is her older brother.

Background
Momiji explained to Tohru, that Momo is his biological little sister. Which shocked Tohru overall. He also explained that Momo looks like their mother. Momo usually mumbles in all of her sentences, and follows her mother around everywhere they go. Momo is probably 5 or 6 years old when Tohru sees her for the first time.

Personality
Momo is described as being a very shy and quiet little girl, and almost never speaks out loud to anyone. According to Momiji, she can't speak Japanese very well so basically when she talks her words she says come out like a little mumble. She wishes that Momiji could be her brother, although she doesn't know that he already is. She took violin lessons, like Momiji, but Momiji's father had to withdraw him from lessons because Momo was asking about Momiji. She secretly likes to watch Momiji play the violin.

Appearance
Momo is a little small girl. She has light blonde hair, and golden eyes. She looks a lot like her mother, which Momiji remarks on, although it has been pointed out that she resembles Momiji as well.

Fruits Basket Manga
While Momiji explained his past, Momo and their mother appeared in the office building.

In volume 13, Tohru had to go to the main house, then walked around the outside because she was nervous.

Then she saw Momo, who said she knew a secret way in. They went into a tunnel in the wall that led to Momiji's backyard. Momo told Tohru that she would come to watch Momiji play the violin. Momo explained to Tohru about how she told her mama that Momiji looked just like her. She asked if Tohru would ask Momiji if he wanted to be Momo's brother. Tohru went in and asked Momiji, prompting Momiji to cry from happiness.
