11 Nin mo Iru!

A family consisting of a jobless father, a domestic mother, and eight children with different personalities. As the title suggests, the family also has a mysterious "11th member".
The eldest son, Kazuo, is a high school student who helps support the family through part-time jobs serving at a gas station and doing newspaper delivery. He clashes with his father, an artsy photographer with no real earning power. The shy, youngest child can see a ghost (the "11th member") but doesn't tell the rest of the family.
