Wholesome and hilarious.
Yotsuba&! is centered on Yotsuba Koiwai, a five-year-old girl who is energetic, cheerful, curious, odd, and quirky — so much so that even her own father calls her unusual. She is also initially ignorant about many things that a child her age would be expected to know — among them doorbells, escalators, air conditioners, and even playground swings. This naïveté is the premise of humorous stories whereby which she learns about — and frequently misunderstands — everyday things.
