He is by far, one of my favorite characters in Fruits basket.
When we first meet Momiji, he seems so happy, yet you wouldn't think that he would have a sad/depressing back story about his mother.
When people cursed by the Zodiac are born, they are born two months prematurely. When Momiji was born two months early, his mother was very worried, and as soon as she held him, he turned into a rabbit. She was so confused and was frightened by the transformation. She tried to love and care for Momiji, but it was too much for her to handle. Sometimes she would snap, and hit or scream at him. Soon, Momiji's father convinced Hatori to erase his wife's memories and ultimately forget Momiji, her only son. To think this happen to momiji, is heart breaking. I wouldn't have imagine that he would have a sad back story
For those who haven't read or seen fruits basket, I highly recommend you should read it, trust me you will love every second of fruits basket
And of course we can't forget the song he made up. "Who's in the forest strolling? The birds and the bees sing Momiji The frogs in the pond are calling, "Momiji, yes, it's true!" The trees raise their leaves together Who needs the sun when we've got you? Who's in the forest strolling? The birds and the bees sing Momiji The frogs in the pond are calling, "Momiji, yes, it's true!""
