Yotsuba Koiwai "Yotsuba"

Yotsuba is depicted as an energetic five-year-old girl with a child's wonder towards even the most unremarkable of new discoveries. She is shown finding enjoyment in nearly everything, and her constant enthusiasm is infectious. Before moving to her present house, she and Koiwai lived with his mother, then before that on an island that is, according to her, "to the left." Nothing is known about Yotsuba's parentage other than that she was somewhere outside of Japan and subsequently adopted by Koiwai and that she is sometimes taken for a foreigner by strangers. She is an excellent swimmer, but not as good an artist as she thinks she is.

The name "Yotsuba" can be translated as "four leaves," and is part of the phrase yotsuba no kurōbā . Her green hair is always worn in four pigtails, giving her somewhat the appearance of her namesake.
