Yotsuba&!

Yotsuba is an energetic five-year-old girl with a child's wonder towards even the most unremarkable of new discoveries. She finds enjoyment in nearly everything, and her constant enthusiasm is infectious. Before moving to her present house, she and Koiwai lived with his parents, 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 orphaned 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.
