AHHAHA. This anime is so hilarious. Its mainly about a boy who is 11 years old, he is super tall for his age, roughly around 180 centimeters, and his voice is SO deep as if he hit puberty. He also has a sister who's only 137 centimeters tall and is only 17 years old, which makes the anime funny. Sad thing though about the anime is that the boy still acts like a little kid, which adults may mistakenly take him as an adult man who is a pedophile toward kids. Very warm humorous anime.
