Yotsuba was abandoned by her mother. Her country of origin is unknown. The small information we have is she came from the left, meaning she could be mandarin. How Mr. Koiwai came to meet her is unknown, but he stated that he just started taking care of her and soon enough, became her (adoptive) father.
She is a lively and lighthearted girl. She takes a challenge and makes it into a fun game. She is always playing, and is very innocent. Yotsuba is very direct, but also kind.
Name Meaning Edit
Her name in Japanese directly translates to "Four leaves" (her green hair and four pigtails).
